Hi,
When I set background->use_ao= false, then this is how it is getting displayed.
When I set it to true, this is how it is getting displayed.
This is a room and the front side is open. There is a light on the ceiling.
What am I doing wrong?
Please help.
Thanks in advance.
Hi @jesterKing,
This is the only blocker I have from get going. Can you please give me any clue?
Thanks
Hi, add the .blend and the Blender version you use, please.
It is nearly impossible to help without.
You can upload Blender files up to 30 MB on Pastall.
Cheers, mib
@mib2berlin this is about using Cycles outside of Blender.
@Subrahmanya we can’t tell what is wrong here. Clearly the light is not working, but without information about how that light is added we can’t tell. Look at how lights are exported in standalone, in the Blender integration, check if you are missing something.
Hi @mib2berlin and @brecht,
Thanks for your response.
I am actually building the cycles scene with code. So, no blender file.
I have JSON representation of my scene. As the above link supports uploading only .blend files, I am pasting the content here. It is a very small scene. You need not look into the geometry part. If you look at shaders and lights, you will understand what is wrong with my scene.
Thanks in advance.

Scene Parameters:
scene_params->shadingsystem = ShadingSystem::SHADINGSYSTEM_SVM;
scene_params->bvh_type = SceneParams::BVH_STATIC;
scene_params->background = true;
scene_params->bvh_layout = BVHLayout::BVH_LAYOUT_BVH8;

scene_params->texture_limit = 0;
scene_params->use_bvh_spatial_split = false;
scene_params->use_bvh_unaligned_nodes = true;The problem is fixed. I was adding a normalmap node without having any normals in my geometry. This was causing the issue.
