Rayraz, To use plugins in Bryce (I can only use sharpen and blur, but others might work), go into the materials lab and set the material for an object to a picture or image texture. Then go into the picture selector (see the Bryce manual if you aren't sure how to do all this). The picture selector will show three large boxes with the picture, the mask, and the result. Each has a down arrow next to it. Click on the down arrow and you'll see a list of plug-in's that Bryce found, and/or the option to point to a plug-ins folder. You can point it to Photoshop's plug-ins folder and press the select button. Now all those plug-ins will be available. However, many only work from within Photoshop and some crash Bryce, so proceed with caution. So far, I can only use the sharpen and blur filters.
