Re: Hdr Light Studio Live For Keyshot Torrent 26
Alfonzo Liebenstein
I faced the same problem using a KeyShot 5.1 Demo version. The current KeyShot plugin seems to work with KS 4 version, haven't tried it because don't have KS 4 installed (only KS 5 in my Win8 machine). When trying the plugin I got the error message saying "the keyshot executable could not be found".
If you are using Windows and comfortable with regedit utility, here is the solution: the plug-in scripts read Windows registry looking for Keyshot 4 settings, and if not found, hard set the path to KeyShot 4 executables. Now the simplest solution is the following (if you don't have KS 4 installed): define in the Windows registry a new key (string type) HKEY_CURRENT_USER\Software\Luxion\KeyShot 4\BinName = "C:\Program Files\KeyShot5\bin\keyshot5.exe".
just today I did an indepth comparision again with KS 5 and noticed that what they sell as photorealistic and physically accutate is a drastic simplification of the light models to maintain render speed.
Hey guys just wanted to let you know that the Keyshot 5 plugin is on the way. We are doing some final testing right now and should ahve it out shortly. Sorry for the delay. If you are interested in testing it PM me and I will see about getting you an advanced copy.
The import option allows you to bring in data from a variety of native CAD systems. These include Alias, Catia, Inventor, Maya, Creo, Pro/Engineer, Solid Edge, SolidWorks, Unigraphics/NX and AutoCAD. Both parts and assemblies are supported and you can import more than one set of geometry to build up your scene.
To date, KeyShot has relied on the tesellation (conversion of nice clean surfaces into a polygon mesh) to get the data into the system and to base the rendering process on. With KeyShot 5, there is now the option to import and, more importantly, use the NURBS data from 3D CAD geometry.
Figure 2 shows a small detail area in a large model that, at full zoom, looks and renders nicely. But zooming into the details, the tesselation starts to show, particularly on round or highly curved features.
Components can be hidden and show from here or directly from the interface. The Project panel also contains all of the settings for Camera, Environment and Material. How those Materials and Environments are assigned is from the Library panel.
For KeyShot 5, the way these are delivered is changing. While the software is still installed with a comprehensive set of basics (from metals, plastics, woods, paints and many more), these can be quickly expanded by taking advantage of KeyShot Cloud.
Of course, you can also upload your own assets and share them if you feel so inclined. Interestingly, this also enables Luxion to partner with vendors to share texture and material information more readily, without bulking out the installation process.
A good example is how the system is installed with a sample of Mold-tech injection moulding grains, but the full set is now available (searchable by grain code name) to everyone. The same goes for the DuPont car paint materials.
That material can then be adapted to specific requirements, which can be saved back to the library. If additional details need to be added, these are assigned as Decals on a per material per part basis, positioned, scaled and ready to go.
Here, KeyShot has a couple of options. The first is the ability to add in physical lights. This helps place lights, highlights and shadows where needed as well as to represent light sources in the model.
They can be mixed as seen fit (in terms of brightness, colour etc.) or more standardised IES format lighting description files are available from many manufacturers. These will provide the exact light emission properties that the physical product should.
With KeyShot 5, however, the system gets perspective matching. We detail how this works below in our workflow, but the essence is as follows. Position a series of axes in the model window to identify where the same axes lie in the photograph.
This means that as a model is loaded, materials added and view changed, the render window updates with a streaming view of the final result. That gives a good, solid idea of what is being worked on and the expected results, before you hit that final render process.
Set-up is pretty simple and requires that on each slave machine, a small app is installed (it works across both Windows, Mac and a mixed environment) and then everything will run from the master licenses.
At the other end of the spectrum, while KeyShot takes full advantage of all of the CPUs/cores available in your local workstation, these can max out and when that deadline is looming, you need a little more push.
Seemingly small updates, such as the sky and sun generator, the perspective matching tools and many others, are perfect additions. They solve workflows and common issues that many might face and allow them to be completed in a couple of clicks, rather than hours spent rendering, swearing at the screen and re-rendering.
The introduction of KeyShot Cloud is a smart use of cloud technologies. Rather than having a separate website where these things are stored, you access them in the application and download them directly and use immediately.
A much better alternative is HDR Light Studio, which starts at 195. This brings a small, nimble application providing a set of tools that are explicitly developed to assist with creating and adapting HDR lighting images for design visualisation.
Essentially, you can either start with a background gradient or an existing HDR image, then use the tools to add in procedural or image based lights. Procedural lights can even be used to locally adjust exposure, colour and saturation.
At all times, HDR Light Studio has a real-time preview window that lets you judge the effect of your edits on either an industry standard teapot or a custom model you load in. The last release saw the introduction of a tool called LightPaint.
Setting up convincing studio lighting in a 3D scene can be an elaborate process of adding and positioning lamps, determining light strength, light color, light angles for reflections and more. HDR Light Studio aims to ease this process, and an add-on to connect Blender to HDR Light Studio has just been released. BlenderNation reviews it.
HDR Light Studio allows you to set up studio lighting in an easy-yo-use interface with powerful tools, and live-connect with your host 3D application for instant feedback. HDR Light Studio Xenon (Drop 1) is the latest version, and a Blender add-on is now available to form a bridge between HDR Light Studio and Blender.
Once you've licensed HDR Light Studio and installed the Blender add-on, you're ready to connect the editors. In the World tab of Blender's Properties you will find a new HDR Light Studio section, featuring a Start, Pause and Stop button. Press Start to establish the connection to HDR Light Studio's environment light canvas. Make sure you haven't already got HDR Light Studio running though, or the Blender add-on will try to start a second instance, resulting in a licensing error, at least on Windows.
HDR Light Studio includes a Blender preset for the UI layout, to provide a user experience optimized for Blender users. You can also easily drag and drop sections to rearrange the UI as you wish, even as autonomous floating windows outside the main interface window, so you can position and size windows exactly as you'd like them to float on top of the Blender window or around it. In case of a dual-screen setup you can conveniently display HDR Light Studio on one screen, and Blender on the other screen.
If you want to use the environment and/or textured mesh emitters for lighting, you'll need to use the Cycles renderer, because Eevee does not support environment lighting or mesh lighting yet, only reflections. You can have environment lighting in Eevee using an Irradiance Volume, but it will not match the crisp ray-traced light and shadow sampling of Cycles. However, the Area lights option is fully compatible with Eevee. You can combine the Area lights with a HDR Light Studio environment for reflections and refractions in your Eevee renderings.
Lights are easily added, adjusted and repositioned in the HDR Light Studio editor. It all works very intuitively. You can choose from a range of canvas backgrounds and light types, ranging from generated procedural gradients to image-based lights and environments. The blend mode of lights can be adjusted to make them blend seamlessly into the background, and you've got much more lighting design options at your disposal.
If you've chosen the option to generate textured mesh emitter lights or textured Area lights, those elements will show up in your Blender scene, complete with a dedicated node setup to ensure that your light strength doesn't wash out the appearance of the light texture.
It's also possible to import your blender scene into HDR Light Studio, enabling you to fully make use of HDR Light Studio's toolset, including the possibility to click on an object and reposition the active light's reflection or light hotspot to a specific surface area.
Once you're ready editing in HDR Light Studio, you can 'bake' the result into the Blender scene, so the emitter textures and HDRI environment image can be saved along with the Blender scene for later reuse without the need for HDR Light Studio. In case you'd like to adjust the lighting afterwards, just fire up HDR Light Studio again and adjust the scene to your liking.
HDR Light Studio is aimed at professional users looking for a dynamic, easy-to-use IBL (Image-Based Lighting) solution. It brings the power of expensive professional lighting solutions like Keyshot to Blender for a much more affordable price. If you've got the budget, HDR Light Studio is definitely a worthy enrichment of your lighting toolset.
Is there a way to shut this resizing off? The zbrush sculpting document size, aspect and resolution (at least in my case) usually have no relation to the Keyshot render aspect and preview size. And as I mentioned, a large zbrush document size almost freezes up the keyshot live preview (and wrecks the aspect ratio and model position).
