[SOLVED] Compilation error in Billboard vertex shader [2.5, D3D11]

[helmut.bressler]

Hello,

 

I encountered a strange compilation error when creating a billboard in the editor:

10:14:27 D3D11Shader::loadVertex(): error in "core/shaders/billboards/vertex/default.vert" file
10:14:27 defines: ,BASE_WIREFRAME,BLEND_SRC_FUNC_NONE,BLEND_DEST_FUNC_NONE,EMISSION_TEXTURE_EMISSION,NVIDIA,QUALITY_LOW,QUALITY_MEDIUM,QUALITY_HIGH,RENDER_MESH_NUM_INSTANCES=341,USE_ALPHA_FADE,USE_PARALLAX,USE_TAA,USE_SPECULAR_LIGHT,USE_ENVIRONMENT,USE_HAZE_SCATTERING,USE_HAZE,USE_ENVIRONMENT_AMBIENT,USE_ENVIRONMENT_REFLECTION,USE_RW_TEXTURES,USE_STORAGE_BUFFERS,USE_SSAO,OUT_GBUFFER_ALBEDO=0,OUT_GBUFFER_SHADING=1,OUT_GBUFFER_NORMAL=2,OUT_GBUFFER_MATERIAL_MASK=3,OUT_GBUFFER_LIGHTMAP=4,OUT_GBUFFER_VELOCITY=5,USE_GBUFFER_AO,OUT_GBUFFER_SPECULAR=g,OUT_GBUFFER_TRANSLUCENT=b,OUT_GBUFFER_MICROFIBER=a,OUT_GBUFFER_SHADING_FORMAT=float4,USE_WATER_ENV_PROBES,USE_WATER_LIGHTS,USE_SOFT_SHADOWS,SOFT_SHADOWS_LOW,USE_OMNI_SHADOW_JITTER,USE_LERP_CASCADES,DIRECT3D11,USE_COMPUTE_SHADER,VERTEX

I think it has something to do with the oblique frustum stuff.

Reproduction should be easy:

 

- Create a fresh unigine Project (under Windows, using D3D11) with Unigine Editor 2

- Create a Billboard node through the editor

- when the billboard becomes visible in the viewport, it should crash (or at least trigger a compilation error)

 

I don't think it is related to the Editor, I also encountered the same issue in Editor 1.

 

I do not need a fix for that urgently, I just wanted to point out that issue

 

Cheers

Hi Helmut,

 

Thanks for the detailed bug report. It was added to our internal bug tracker.

It can be easily fixed by modifying data/core/shaders/billboards/vertex/default.vert. Just add after line 7 following string:

INIT_OUT(float,0) // line 7
INIT_OUT(float,1) // add following

Thanks!

Thank you Silent!

Fix for this issue will be available in next SDK update.
