I’ve submitted this as a bug report to Unity, but haven’t heard anything back so I thought that I’d feel out the community to see if they’ve encountered anything similar.
I am running Unity 3.3 in OpenGL mode on a Win7 64-bit PC with a ATI Radeon HD 4300/4500 Series GPU ( Catalyst Version 11.5). Soft shadows, or for that matter, any shadows do not appear when using OpenGL in forward rendering. Deferred shading produces shadows but the entire scene is decorated in odd hash patterns.
When running in DirectX mode, the shadows appear properly. Unfortunately, I am required to use OpenGL due to a need to use the ability to upload a texture directly to the GPU (which does not exist in DirectX Unity).
Has anyone encountered anything similar to this? If so, have you managed any workarounds?
