Every 3D model are adjustable, just drag and drop a 3D model to the canvas, then you can change the camera angle and object size. I think both normal and EX version are include some preset 3D model in the material.
The 3D model function gets a huge update as well. Material include a lot of new color pattern. (I think around 30sec to 1 min to convert one page, depend on how many layers you have in a file.) The new layout looks nice and clean. It takes some time for it to convert to the new version. This version is backward file compatible with both page files and story files from ver4. The new balloon function are pretty easy to use as well. The text and balloon now are group together. I still need to test out the color mixing tool. Huge selection on the pattern brush, I have fun to try it all out. The new brush and pen tool add in a lot of option, but I find myself pretty much stick with the old one I like. The new layer blend mode is similar to Photoshop, multiply, screen, overlay, color burn and color dodge, etc are all included. It picks up the color already on paper and blend in the new color just like traditional watercolor brush did. The paint brushes mimic the real brush quite well. Using brush range between 50 to 100 without problem. This drawing I working on is 11 x 8.5 600dpi. No more brush lagging when using bigger brush size. The brush engine is much better then the old version. I import a line drawing from MS4Ex to MS5Ex and try out the new paint brush. The new watercolor and oil paint brush are the major new function. The layout of Manga Studio 5 pretty similar to ver4. In Japan this is known as CLIP STUDIO from CELSYS, the same people behind Comics Studio/ Manga Studio. I have a chance to test out the new Manga Studio 5 Ex before Smith Micro launch it at SDCC this year.
