OpenPDN in Plugin Developer's Central Posted June 18, 2011 · Edited June 18, 2011 by Boude I tried a 10000x10000, PDN froze, but with 5000x5000 it worked. First it started finishing (took time), then it started initializing (also longer then normal), but the rendering process took only a split second. Done with the blur effect from above on some clouds. My guess is I was too impatient with the 10000x10000. I wonder what happens in the finishing and initiating parts of the effect rendering cycle and how does my effect come in? Maybe I should move some code around to do the rendering at the correct time, note: it is an Effect, not PropertyBasedEffect. By the way, I want to take in no way credit for the rendering of the image and the compiling of the code, that's all OpenGL. All I did was call a couple of methods.
