Hi Experts, I am trying to export SketchUp material. In the file …\SketchUpAPI\model\material.h, there is enum SUMaterialType with three material types. /** @enum SUMaterialType @brief Indicates material type. */ enum SUMaterialType { SUMaterialType_Colored = 0, ///< Colored material SUMat…

I have the same questions. Who can answer the question?

Hi Dan, For Colorized texture, I have no questions. For the material type “SUMaterialType_Textured”, we only assign a texture onto a face. However, we still get color information from the function “SUMaterialGetColor（）”. The question is what the color is? Is it calculated from the pixel of texture…

According to Ruby API document, the answer is yes. Please see the link: [image] Class: Sketchup::Material The Material class represents a texture or color that can be applied to Drawingelements. I assume the C API should be the same.

[image] xqtyler: The question is what the color is? Is it calculated from the pixel of texture image file? Do you know what the color is for the material type “SUMaterialType_Textured”? And the Ruby API doc says … If it uses a Texture, this will return the average color. So yes, there is…

Hi Dan, Thanks for your detailed explanation. I am using the 2018 C SDK release (C API ver 6). I have no question about the function SUTextureGetAverageColor(). My question is: For the material type “SUMaterialType_Textured”, we only assign a texture onto a face. However, we still get color infor…

Hi, I can’t see a reason for SUMaterialGetColor to return the average color for a textured-only material. Can you post a minimal code example that duplicates the issue?

I think I see what’s happening. When you set the texture on a material using SUMaterialSetTexture, the average texture color is applied to the material. So when you call SUMaterialGetColor, you get this average texture color back.

So the question that follows is, is this expected behavior or is it a bug ?
