ofxAssimp vs. ofxAssimpModelLoader - normalized tex coordinates

[dimitre]

I'm porting some code from ofxAssimpModelLoader to ofxAssimp
I use to load some 3d objects and the change the texture to fit content (to simulate led panels)

I've noticed in ofxAssimpModelLoader it is using pixels coordinates, if I have a texture in original model
and with ofxAssimp the whole model is getting the top left pixel color, so I suppose it is working with normalized tex coordinates.

Is this intentional? if yes how can I change to pixel coordinates?
Thank you

Hmm, I think it's a bit more complicated in ofxAssimp since each model can have multiple textures so the default is Texture2D which is tex coords 0 -> 1.
Try importing with ImportSettings and ImportSettings. importAsTex2d as false

openFrameworks/addons/ofxAssimp/src/Source/ofxAssimpSrcScene.h

Lines 34 to 47 in 24d166e

	struct ImportSettings {
	of::filesystem::path filePath;
	int assimpOptimizeFlags=OFX_ASSIMP_OPTIMIZE_DEFAULT;
	bool importAsTex2d = true;
	bool importTextures = true;
	bool importAnimations = true;
	bool importMaterials = true;
	bool fixInfacingNormals = false; // aiProcess_FixInfacingNormals
	// bool importLights = false;
	bool convertToLeftHanded = true; // aiProcess_ConvertToLeftHanded
	std::vector<std::string> excludeNodesContainingStrings;
	unsigned int aiFlags = 0; // ai process flags, ie. aiProcess_FixInfacingNormals
	};

ImportSettings is;
is.path = "pathToModel.fbx";
is. importAsTex2d = false;
myModel->load(is);

Most models use normalized coordinates so the default is to load Texture2D. Maybe we could run through the mesh and determine if there are texture coords greater than 1.0 and then load ARB textures?

Great it works! thank you.
in ofxAssimpModelLoader it changed to pixel coordinates if the texture was loaded correctly. I'm not sure if it was intentional but I was used to it, so my ofFbo textures would just work there.
