I'm using Unity3d Indie and currently considering to get my hands dirty with shader code. Are there limitations on the Indie version regarding shaders ? What problems can I expect ? Can I solve these problems ?
I figure there could be some restrictions that make producing powerful shaders tough. Let's assume a static variable like LightPos_1 is not available. That would be a total blocker to shader development. Do I have to expect a drawback like this ?
Moreover any advice is welcome. If you know a good tutorial / tool, please let me know of it.
I've just found this http://unity3d.com/support/documentation/Components/class-RenderTexture.html
I am shocked. How can I implement advanced effects without rendering to textures first ?
