Summary	0005505: Generated deferred diffuse texture is not never used (and probably normal neither)
Description	When using deferred shading, the diffuse texture produced is not used later at the lighting pass (And I'm almost sure normal info is not used neither). That's happening to both Units and terrain rendering
Steps To Reproduce	You can just edit cont/base/springcontent/shaders/GLSL/ModelFragProg.glsl, line 139: - gl_FragData[GBUFFER_DIFFTEX_IDX] = vec4(mix(gl_FragData[GBUFFER_DIFFTEX_IDX].rgb, nanoColor.rgb, nanoColor.a), alpha); + gl_FragData[GBUFFER_DIFFTEX_IDX] = vec4(mix(gl_FragData[GBUFFER_DIFFTEX_IDX].rgb, nanoColor.rgb, nanoColor.a), alpha); + gl_FragData[GBUFFER_DIFFTEX_IDX].r = 1.0; After recompiling you can launch the game and check that the units are not red.

Kloot 2017-03-30 16:28 developer ~0017407	That is intentional because the actual shading is performed by games (if they optionally choose to insert so-called custom deferred materials), Spring does not know or care which of these textures are used.
