View Full Version : Glass Shader complexity?

I'm trying to learn shader creation, and running into a BUNCH of problems.

One thing is...my shaders are growing HUGE...perhaps 30-50 object/items. I'm sure this is REALLY slowing down my renders.

I'm just trying to shade a NURB coke bottle that I have created and having NO luck with it.

Do you guys have a limit you try to impose on yourself for shader complexity? Does 30-50 items in a shader network sound high? It sure seems complex to me.

why not download some glass shaders from AW or use the glass shaders in the Shader Library...that should make things more clear

Hi!

This one is good:

Go to How to create a realistic glass shader.


have fun:)

Yes, both are OK tutorials...but the Shader gets MUCH more complex because my object is a NURB with non-uniform isoparms, and because I've got labels on my object. I cannot do things like projections because it gets double projected through both the inside and outside edge of the glass.

Labels seem to add a HUGE amount of complexity. Then once you try to add things like a diffuse, specular, and refractionIndex map...the shader becomes unweilding.

I'm just not sure if I'm going about this the right way, or if there is a better way (perhaps redering in passes, etc).
