| Summary | 0006245: "shadow" lua materials | ||||
| Description | I'm playing with CUS capabilities to supply custom "shadow" materials/shaders. In particular the use of the GL.FRONT culling (during shadow pass) is looking good. With that kind of culling I was able to get rid of any z-biases (positive during the shadow pass or/and negative during the shadow mapping) and get excellent visual results without any shadow acne. Apparently the engine expects GL_BACK culling to be there during the whole shadow pass: https://github.com/spring/spring/blob/maintenance/rts/Rendering/ShadowHandler.cpp#L381 With that two questions: 1. Is GL_BACK culling really good idea? For units and features GL.FRONT works just great 2. Is there a way to restore expected GL_BACK after I have completed shadow pass for custom "shadow" materials. (Clearly I don't want to do that individually after in post-DisplayList). Because GL_BACK culling is not restored I get the terrain shadow artifacts like the one attached. | ||||
