  1. Hello, guys, I use Vray for Sketchup I have found two very annoying issues: 1. I added infinite plane on my model, but the rendered output comes out like this: with a lot of whitened areas(see the 2nd image) 2.I used the grass texture embedded in v-ray material library, it shows in sketchup like normal grass texture, but when I rendered it, it comes out like a piece of green linen cloth(I use the default setting, not sure if it is the issue).(see the 1st image and the 3rd image) I also attached images at the end of the post to show what I talked about. Much appreciate if you could provide any advice!
  2. Hi, Garland, Thank you for your advice! On "pushing whites and blacks", do you mean to push the "curve" in PS or to adjust the "contrast"? which exact command did you use? Also, what do you mean by "strength values", is the strength value set in Vray or PS? Thank you!
  3. Thank you, Lewis. I did watch their video, but it seems that different materials set differently so that I could only make a trial and error by changing each setting. But thank you so much for your advice!
  4. Hi, Guys, I am new to this community! Nice to meet you all! I have been using vray for Sketchup for a while. The biggest problem I have is that the rendering looks not realistic as it should be(what the renderings show on some website). I downloaded different material layers from Poliigon, it prepares each map for you: Ambient Occlusion map /Diffuse map / Displacement map/ Gloss map / Normal(bump) map. I applied the material to my drawing and rendered it, but... it still not look good. I also tried to use the materials that in the vray library, but it come out to be very plain, I mean it does not have details, texture and looks more like a piece of 2d drawing, looks really weak in 3d visual sense. It become better if for each material I added a bump map, but the light still seems not quite right. I feel it to do with my settings for reflection, refraction parameter... I know some basic IOR value and I understand the basic ideas of glossiness, fresnel, but it just does not look good. I know it is a broad topic, but is there any tutorials talked more depth into how to set the parameters? I know each material has different settings, and it sometimes confused when you were watching how it works in some videos and did it by yourself but it come out totally different.. Thanks all!
