Just went through the vids and some tutorials and trying out unity3d now.
Is there a library of materials similar to 3d appz where they have a preset for glass materials etc.
I’m trying to see if I can make realistic looking cars for real time previews. Thanks.
Most of the games with “realistic” cars have specific custom shaders for car-paint and glass. You might want to look into custom shaders if you’re looking for realism.
There are a few free shaders out there but most are in HLSL or CGFX as opposed to what Unity seems to be calling a mix of their proprietary Shader-Lab and CG languages. Very understandable given the ability to simultaneously develop for Mac and PC.
Nvidia has shaders you can look at and start from in both HLSL and CGFX at their shader library: NVIDIA Shader Library
You can get started writing shaders with their FX Composer tool: FX Composer | NVIDIA Developer
But… you’ll still have to take what you’ve learned and apply this to Shader Lab in Unity. You might check the shader page of the Unity wiki to see if there is anything there that gets you closer to your goal. Oh… and I belive you’ll need Unity Pro.
To make custom shaders? Nope. Only if you need rendertextures.
