Yo guys, this time on @RenderRam , I'm covering BUMP VS. GLOSSY, and why it's important to know when to use each one! This rule applies to most 3d softwares and rendering engines. Check it out!
Fantastic!! very well explained, shed light on something so damn important. Although I am a hardcore Vray user I find it very useful. Keep on posting such knowledgeable stuff and thank you!!
Works because what defines any surface in reality is the roughness. When you use the bump, you are defining the level of roughness without using the glossiness ou roughness property of the shader, though the bump is much more render expensive. A trick to render the bump faster, is to put the bump in a gradient and use a dot product as an input taking the camera as reference. In doing so, the bump only appears in the geometry facing the camera, speeding up the render time.
I'm learning fstorm and watching some of your videos to understand better, I'm making a scene to learn materials and I tested this glossy bump technique on a wall, it was very good, but when I changed cameras it was totally different, do you recommend using this when it would be a product render, just a studio or how to do it? Hug from Brazil ! And thanks for all vídeos, its a treasure!
Hi, congratulations and thanks for your videos! I have some questions: 1. At 3:52" what is your Falloff map setting? Is it default? 2. At 5:40" I would like to know which wood number Arroway used and how you set each ColorCorrect map to Difuse/Reflection/Refraction and Bump? Thank you again!
I like your vids here. can you make a video on how to creat bumb, normal, displacement from material and when to use them and to generate seamless texture as well. thanks and more power!
thanks alot! would love to see more Material Tutorial Videos. Could you show us how to make wood look realistic on a building far away .... where the texture is quiet visible in the distance. It alway looks like a color not like wood material :-(
Huuu that’s a VERY nice question! Far away objects have a bit different logic how they appear in render, will see to make a video about that definitely!
