Hello ive found the issue(why i was getting the crashes) its mainly due to use of polygonal PV fields..i replaced them with Rectangular ones and the crashes stoped occuring...there is another issue id like you to look into..Module layout is buggy when importing a modified Shading Scene. as it doesnt import correctly..unless i make a new project with a new scene(creating it again) i dont get corect PV planes(or missing some).
