Shader release: Per Object anti-aliasing

[Amaan Akram]

Hello,

I've just uploaded a shader that allows you to set per-object anti-aliasing/sampling with Mental Ray. This has been written because I can't seem to find the equivalent from Ctrl.Studios.

http://www.warpedspace.org/plugins/objSampling/objSampling.zip

Softimage 2010+ only, Win32/64.

If it doesn't work, please see the readme included in the package.

Thanks amaan ! That should have been by default within XSI ! 

does it support also rasterizer sampling parameters ?

Hi Harry,

I totally agree that this should be in there by default, and it is very easy to implement as well.

I will add rasterizer support too. If you think of anything else, please let me know.

Wow, nice one Amaan. I can try compiling that for you on Linux if you like?

Thanks, Andy. I'll pop the source across to you for linux.

Harry, Rasterizer support has been added. Please do take a moment to test it out. 

I've also edited the SPDL to allow for animation of the sampling parameters. This could be used to link, say, an object's distance from camera to anti-aliasing samples, which isn't possible with current implementation in Softimage.

Just tried and the shader can't be found.

I have checked that the DLL is found via the plugin manager.

I am under Vista SP1. 

Did you use any special library to compile it ?

no special library is required. The reason the dll is not being found is because of one or both of the following:

a) the microsoft redistributalbes required for this shader to work have not been installed

b) you may have the 32-bit dll in the 64-bit folder or vice-versa. This happens quite a bit because Softimage doesn't detect the dll version correctly when installing SPDLs. Note that this happens even when the plugin manager is able to find the dll. One way to fix it is to manually copy the dlls across from my zip file in to the User/Applications/bin folder

hope that fixes the installation issue.

dll build from debug mode maybe ?

it's definitely a Release build, and I think it is likely to be a case of Softimage not installing the right dll in the right folder, or the Microsoft Redistributables issue. Th incorrect dll install issue only happens when I try to ship both 32-bit and 64-bit dll's together in nt-x86 and nt-x86-64 sub-folders. I'll package them independently from now on.

Thanks for sharing Amaan - this will be very useful.

I have tried to swap dll between 32 and 64 bits version. No sucess.
I am sure I got some library missing.

Can you point me to a link for the Microsoft Redistributables are so I can test it ?

Hi Harry,

Assuming you are on x64, please install this

hope this solves the missing libraries issue

thanks for testing.

Thanks it does work now.
However when I switch to rasterizer it seams that XSI get confuse as soon as I switch on Scene-Wide Sampling.
Switching it off doesn't solve it and the global settings does'nt influence the render anymore.

When being in scanline/raytracing everything seams to behave as expected !

Thanks, Harry. 

>XSI get confuse as soon as I switch on Scene-Wide Sampling

Scene-wide Sampling should set the rasterizer samples for all objects except the one you have got selected in the Objects List. If Scene-wide is unchecked, your objects should pick up the shading samples from the Render Options PPG. That's the theory, at least :)

I'll check
