None of my experiments work as expected, so I'm going to tell the list what I expect and hope to be corrected. (yes I have read and kept all the messages posted recently on this topic. Is there a sample or a template? If so I could study that first, but I can't find anything) What I understand is this: I can map a greyscale bitmap to a surface and use the value of grey at any point to specify the displacement of the surface at render time. So Realsoft will read my bitmap and assign values of 0-1 depending on the greyness of the image. Most people then scale it to between -1 and 1 (so a value of 50% grey will be no displacement) then scale it again to an appropriate size. For example, the attached image is 50% greyscale with numbers scribbled on it at different values of greyness. Correctly mapped, this should not change my surface except at the numbers which will be extruded at render time either out or in, depending on their value of greyness. Or have I misunderstood the concept completely? I've also noticed that .png works diffently to .jpg (I should say doesn't work differently). Was that just me or is it an issue?
