Christiaan Posted March 6, 2013 Share Posted March 6, 2013 Same model, same render settings. Different view projection = different colours. Why? Quote Link to comment
bcd Posted March 6, 2013 Share Posted March 6, 2013 Could be that your view is parallel to your light source. Try rotating the light a touch to see if things improve Quote Link to comment
Christiaan Posted March 6, 2013 Author Share Posted March 6, 2013 All elevations look the same. This isn't so much a question of how to fix it as why does it do it like this in the first place? Quote Link to comment
Kevin McAllister Posted March 6, 2013 Share Posted March 6, 2013 Christiaan, What are the render settings? I've seen this often. I always thought it was because the Cinema 4D engine has proper colour management and Vectorworks itself does not.... Kevin Quote Link to comment
Christiaan Posted March 7, 2013 Author Share Posted March 7, 2013 So the render settings are: Fast Renderworks background, Hidden Line foreground. Lighting is set to defaults (for both). Quote Link to comment
Christiaan Posted March 7, 2013 Author Share Posted March 7, 2013 By the way the 3D version is the correct colour. And if I use OpenGL for the 2D elevation it comes out the correct colour also. Quote Link to comment

Actually, now it is a case of how do I fix this? I thought this was just some kind of default behaviour and a setting or two would change it but I think it might be a bug. Quote Link to comment
D Wood Posted March 11, 2013 Share Posted March 11, 2013 Christiaan I use 50% ambient brightness, daylight temperature (6500k) and 120% for sun brightness. Your elevations and sketch may be underlit. Quote Link to comment
Christiaan Posted March 12, 2013 Author Share Posted March 12, 2013 But they're both using exactly the same light settings (the defaults). Quote Link to comment
D Wood Posted March 13, 2013 Share Posted March 13, 2013 I wasn't offering my standards as a solution to your problem necessarily, but the default indoor lighting level you are using is perhaps wrong for external depictions, and I have found that the ambient light level of 35% is too low, so maybe the default levels are affecting the elevations and perspective in different ways.

Christiaan Posted March 13, 2013 Author Share Posted March 13, 2013 so maybe the default levels are affecting the elevations and perspective in different ways. If so I would consider that a bug. Quote Link to comment
Alan H Posted March 13, 2013 Share Posted March 13, 2013 Same model, same render settings. Different view projection = different colours. Why? I'm glad you asked that question I'm having the same problems I thought it was just my settings, I spent several hours trying to get 2D elevations, from a 3D model to look the same colours, without success, using renderworks. I notice that moving the light source does help a bit tho, but far from what i need. Quote Link to comment
VincentCuclair Posted March 13, 2013 Share Posted March 13, 2013 But they're both using exactly the same light settings (the defaults). You know, I don't think this is true however not your fault though.......I think the problem is the fact that you are using an ortho-view, in perspective views only part of the light is reflected back at the viewer while in ortho-view (which basically is a none realistic view) a much larger fraction of the light is reflected back at the viewer and this makes it look 'lighter', mind this is only my theory, I don't really know how the function is programmed to reflect light. You could try this theory by making the ortho-view into a perspective and see if there is a difference. Quote Link to comment
Christiaan Posted March 13, 2013 Author Share Posted March 13, 2013 They're using the same light settings in the sense that the lighting interface settings are exactly the same. This is what happens if I change the orthogonal to perspective. A wee bit darker. Quote Link to comment
VincentCuclair Posted March 13, 2013 Share Posted March 13, 2013 (edited) On a side note I don't use ambient at all anymore, I find these settings to give the most realistic renders. (You can fiddle with emitter brightness and HDRI background brightness to get lighter or darker images and I believe, vary shadow darkness) Edited March 13, 2013 by Vincent C Quote Link to comment
VincentCuclair Posted March 13, 2013 Share Posted March 13, 2013 This is what happens if I change the orthogonal to perspective. A wee bit darker. If the textures are reflective in any way this phenomenon is likely to be more acute. Quote Link to comment
Christiaan Posted March 13, 2013 Author Share Posted March 13, 2013 Thanks Vincent. It became a non-issue because I ended using entirely different settings anyway. But I think my original point still stands. Why does it do this? It shouldn't. Imagine a new user coming across this. There's no logical reason for it to behave this way. Quote Link to comment
