Hi--could use some help from some experts. I'm running iclone 4 pro. For some reason, I'm locked out of pixel shading; can only use quick, smooth and wireframe--they're the only options in the drop down in the preview screen and I can't enable pixel shading in the preferences. Only quick shading is allowed.

The OS is Windows. 2G ram.

Any thoughts?

What graphic adapter and driver are you using?

Ah, that explains it. Many thanks!

I have some question regarding shading. For instance I work in some project (in Iclone4.3) with a cylinder prop in quick shading mode. Cylinder prop is "acting" laser beam so it's only visible for a second or so but when I switch it to Pixel Shading the cylinder does not show up at all unless I keep a timeline opened and cylinder selected, then it only shows up. But of course when I run it in Quick Shading mode it appears with no problem.

The solution so far is to erase the cylinder and then do it again in Pixel Shading mode, but does anyone have any other solution?

EDIT I reopened it and when switched to pixel shading it's visible.
