hello.

I’m creating a sketchup importer for opengl.

My problem is that i multiplied all the point in the models for the word matrix , and i translate for the translation vector for visualize all without any local coordinate system.

Each node in the importer indeed can have a parent , next i multiply the parent matrix for the current matrix and so on.

But I have a problem on the texture UV , must be multiply for the world matrix?

or the problem is elsewhere?

What is your problem? I can’t tell from the description you have posted.

thanks, but i’m at work , tonight i send you two images of the error.

thanks
