Not to worry, my example of using Vue 4 on a G3 is not indicative of our testing -- Im in sales, not an engineer -- I dont get one of the shiny new muscle Macs. If its just a matter of high polygon count and not specific issues of specific types of imports, then it should be easy enough to test. We have volumes of models to experiment with internally. Ill discuss with the engineers. Best regards, Lynn Fredricks e-on software
