Andy Broomell Posted May 28, 2020 Share Posted May 28, 2020 (edited) Here's an issue I've had for years... I'm curious if anyone knows why it happens or if there's a fix. The basis of the problem is that areas of a texture that are semitransparent seem to also get darker in value when rendered. For example, here I have an image prop that is a soft-edged yellow circle (imagine perhaps it's the halo around a light or something). It should look like this: But when rendered in Renderworks it looks like this: The pixels should only range from yellow to white, where is that darkness coming from?

markdd Posted May 28, 2020 Share Posted May 28, 2020 If I change the colour shader to just plain yellow and then I get this result. Do you think that there is some sort of "interference" with the image pixels from one image to another that is causing the shadow effect? Quote Link to comment
Andy Broomell Posted May 28, 2020 Author Share Posted May 28, 2020 It does seem to be something like that. Strange... I wonder if someone from Vectorworks can elaborate on what's happening with the combo of the two images' pixels. I should mention that I'm not typically using a simple solid-color image like in the example, but in this case changing the Color shader to plain Color would be a workaround. Quote Link to comment
EAlexander Posted May 29, 2020 Share Posted May 29, 2020 Is ambient occlusion coming into play here? I wouldnt think so, but it looks like it. *longshot Quote Link to comment
Andy Broomell Posted May 29, 2020 Author Share Posted May 29, 2020 Looks like it happens even when AO is turned off. Quote Link to comment
Jeff Prince Posted June 3, 2020 Share Posted June 3, 2020 Strange, I'm interested in the solution as well. Quote Link to comment
