I'm new to sketchup and Vray so not really sure but you can try reading this:
http://www.vray.com/vray_for_sketchup/manual/choosing_different_render_engines.shtml
It could be something with the iraddiance map settings
"When Min Rate and Max Rate are too low, "leaking light" happens even if the objects are joined together"..you will find where they talk about this somewhere in the middle
I tried readjusting the physical camera and environment settings like you suggested but i still can't figure out how to get rid of that washed out look..any other suggestions?
valerostudio: I tried using the exterior highest quality settings earlier when you asked me to..like i said the problem was still there..what exactly do you think i need to change in the IR map settings because i tried a lot of different IR map settings and that didn't seem to fix the problem
stefanq: I tried that as well but didn't help
Panixia: I raised the HSph subdivs and the light cache subdivs like you recommended..it did help but when i saved to jpeg the problem was still there..so i guess the only solution is to save to exr first like you suggested then merge and save it to jpeg..i tried that and it worked..i couldn't fix the transparency issue earlier but it's working fine now..however when i try to change the mode to 8 bit the image gets darker..so what should i try to do now?..just play with the gamma and exposure settings?
Alright nm..i changed the method to gamma and exposure and that preserved it..so that pretty much fixed the issue that i was having trouble with and now i know that it had to with color mapping..that's why whenever i was trying to change other settings it wasn't helping much..
Here's the final image..it's little washed out..you were suggesting i change the physical camera and environment settings earlier but not sure exactly which ones..but anyways i can play with it and figure it out..thanks again panixia for the help, really appreciate it
Panixia: I tried your suggestions and it did seem to fix the problem a bit..it's still slightly there but def a lot better..but another problem now is when i save the scene to exr the sky doesn't show..it's like an empty layer in photoshop..also the exr files are a bit too large and i'm not really used to working with it..so is there any other way to fix this but save the images to jpeg?
I tried going through the tutorial you sent me but it was a bit confusing but basically what you suggested is one way to do it and there's another way (Burn in gamma 2.2 setup) which i can't seem to figure out how to do in sketchup because the vray options in 3ds max are little different
I ended up using brute force and light cache again..it does take longer to render and a bit noisy but overall the quality is better and i can save it to jpeg
So if there's anything else i can do please let me know and thanks for the help
Panixia: i thought this was a common problem and more experienced users have already figured out why vray does that because as you can see the scene is extremely basic..and like i said i've tried many recommendations to fix the problem and changed a lot of the settings that were supposed to fix it but it didn't..i was thinking it might be something more obvious and not about a particular setting..
but anyways..here's the image again with the vray default settings (not the exterior high quality preset)..just the default settings..
and here's the settings like you requested..
Roland: I'm not sure what are you talking about..i think you're talking about something different from the issue i'm having trouble with..
Here's the scene again without the boxes..my problem is the lack of smoothness on the surfaces..it looks like a bad compression jpeg file
Panixia: i'm using the default high quality exterior settings..haven't changed anything in the color mapping settings in that earlier picture..but tried changing them and again same problem..like i said it seems like it's always there no matter what i do or change
I also tried saving to .exr like you suggested but didn't fix it
Thanks for the reply.
I've tried many different settings but the problem was always there..i don't remember which settings were used for the images i posted earlier..but here's an image with the highest quality exterior settings..i can still notice it and doesn't look smooth enough to me..i'm using just basic grey colors in sketchup as the material and yea just the vray sun
I'm using sketchup pro 2015 and vray 2.0.25 win 64bit btw
Hi everyone, i'm new to sketchup and vray. Still learning the basics and running into some problem with the vray renders. I've already tried to find an answer to this problem on the net but couldn't find anything that would actually fix it. Tried a lot of different settings and suggestions but still nothing. I keep getting what seems like low compression problems with JPEG. I've tried saving to TIF but same problem. I'm not even sure what exactly this problem is called..blotchy/splotchy surfaces?..I'm making a very simple scene with just some boxes in the shadow and the shading doesn't seem to be smooth and something is off.
I'm using irradiance map and light cache. Tried brute force too..it worked little better but there's more noise and it didn't completely fix the problem. It was still noticeable just not as obvious and i don't like any of the renders i'm getting. Can someone please tell me what's going on and how to fix this. It's starting to frustrate me since i'm working on a very basic scene yet can't fix this simple problem.
Here's some pictures of what i'm getting.
Tried again with different many different settings and did lots of renders but the problem is always there no matter what i change..tried changing the Hsph Subdivs and Interpolations sample. It improved it a bit but the problem still there and still look crappy no matter what settings i change
