Apparently it might have something to do with scaling the model ? I didn’t really understand the solving answer by Jaco_Pretorius on one of the topics you linked me, which seemed the most similar to mine ( White dots on texture). However I have not followed the Orc course yet (before the dragon sculpting course I have followed through the Learn 3D modelling for beginners course)
What is the lesson where Grant teaches about measuring things ? I haven’t seen it in the titles of the Orc course.
