ASSIGN SURFACE TYPE! WARNING

To remove this warning click HERE and follow the instructions in the Instructions.txt file.

REDUCE GLOW

When you export from Sketchup into Crysis, the resource compiler sets your material diffuse settings to 235,235,235 by default. However, the Crysis default is 186,186,186. To improve your materials, switch to the Crysis default...Or experiment with the diffuse settings to see what looks the best:

Incorrect diffuse settings

Crysis default diffuse settings

DETAIL BUMP MAPS

You can give your materials a certain texture to them, for example, make them appear like concrete or wood. You do this by applying a bump map in the Detail box - see below: 

1. Assign a surface type, eg concrete to get rid of the ASSIGN SURFACE TYPE! warning.

2. Assign a Detail bump map from the folder: textures/detail_bumpmaps. eg metal_ddn.dds:

metal_ddn.dds


3. Under Shader Generation Params tick Detail bump mapping

4. Under Shader Params play around with the following settings:

Detail bump scale: (how bumpy the surface will be)
Detail tiling U and V: (the scale the texture will be mapped. A setting of 100 will make the texture tile smaller than a setting of 1. I usually go for around 10, however if you've used the Sketchup default white material, you may need to use around .05
