Glass and UVW Maps

[mportokalli]

Hey guys,

I have recently completed my week 2 task but with a few holes in the model. My first issue is scaling each individual object in 3dsMax. I'm doing the B.Pav and I am struggling to align and edit individual faces with UVW maps without mucking up the whole look of the model because most of the meshes are connected and change together, is there a way around this so that editing is easier? I am also struggling to wrap my head around creating a glass material and sending it through to C.Engine, it is my understanding that we have to model the glass components in 3dsMax because they aren't in the B.Pav model but how would I go about creating and exporting so that it shows up in C.Engine? The model looks empty without it.

Cheers,
Matt

Hi Matt,

You can edit the UVW maps of individual faces of an object while in the modify menu. With the object selected go to the 'Selection' tab and choose 'polygon' (pressing '4' while the object is selected will do the same)

Now you can choose individual faces or any combination of faces by holding Ctrl and left clicking on the desired faces. Then in the modifier list choose UVW Map as normal and you will be able to edit only the selected faces. If you need to edit more faces after, simply add the 'Edit Poly' or 'Edit Mesh' modifier, depending on whether you are working with Poly's or Mesh's, and keep selecting faces to UVW Map.

For the record, in Ros's tutorials and notes she uses Poly's and in mine I use Mesh's but they are essentially the same thing.

As for the glass elements in B.Pav. You would model them as you would any other rectilinear object, with boxes attached together, would be how I'd do it. For glass to look good in Crysis you will generally be editing the Crysis material so all that is really needed in Max is a simple placeholder texture to use as a guide when UVW Mapping. Once exported to Crysis you'll edit the opacity and various other setting to get it behaving like glass. I'll post on my blog sometime tonight some settings for glass to use in Crysis, but just keep it simple in Max with a standard diffuse texture as a placeholder.

Hope that helps

Hey Jules,

Thats brilliant cheers for the heads up on UVW maps and I will have a crack at your glass tut as well!

Cheers,
