Textures - Understanding a tutorial

Support Materials and Textures

Hi
I’m trying to follow this tutorial to get an understanding of some textures, but he doesn’t really explain anything like what the nodes do .

I was wondering what part makes the ball actually looks like a chunk is taken out of it, as mines just like the texture but still all flat when you move around it?

Thanks !

at 2:23 , he connects Math node into Displacement input of Material Output node. That displaces the geometry.

I thought that but mine still looks pretty flat compared ? I don’t have the bake image texture could that to do with it?

If anyone has any recommendations of good talk through tutorials on textures please let me know! :slight_smile:

Experimental feature set needs to be enabled, and the material set to use either true or both as displacement type. It defaults to bump which looks flat, as it fakes the uneveness.

A few things about posting

  • You’re asking for troubleshooting help and the cause of the problem is contained in your file, not in a tutorial, so prepare and upload an example file in the starting post every time your questions involve one
  • Never link to a video and assume anyone is going to sit and watch through it, especially just to figure out what your problem might be and when you fail to include a .blend. Video links with a timestamp so people can jump to the relevant parts
  • Know what you’re learning from. What you linked to is not a tutorial, it’s a timelapse that is titled as a tutorial. If you have trouble following that, no wonder because when rated as a tutorial, it sucks and extra minus points for misleading title, which equals craptastic+. Find actual tutorials that are meant for learning and are easier to follow.

Basically what @JA12 said.
You missed the first 20 second of the video where he creates subdivision surface modifier and enables both (displacement and bump) in material settings.

Also amount of shaders are redundant for this material. It already hangs when a parameter is changed. You should be able to create this material with just 2-3 shaders. Shaders are expensive to calculate, so think twice when you add them.

Thanks, it’s already set to experimental but I missed the bump change thanks!

Sorry no time stamp I didn’t really know where the problem was so wouldn’t know where to direct, called it a tutorial as it was called one. Finding it difficult to find good ones for me, as I said just delving into materials properly so trying to work out the best way I learn them.

Thanks for the advice :slight_smile:

That wasn’t the point. It would be silly to expect you to know where the problem is. Those and tips below are for your future posts.

If you read the threads on the support forum, most concentrate on describing the problem, and the cropped images they provide only contain what they’ve just said in image form, and no additional information. Then they ask why this happens, or if anyone has an idea. That is the wrong way.

What you need to do is describe the problem, that part is ok, but it’s not the part that gives you answers so don’t waste a lot of time describing it in words. Use visual aids, which are clearer, and when you only point to them instead of repeating what it shows, they also reduce the amount of writing you have to do. Those are helping you to write your post, they don’t help others to give you the answer.

The most important part is providing the tools for others to help. That means an example .blend so one can jump in and either tell you the answers after eliminating 15 other possible causes. It also means them including visuals because they had the file. Or, at least provide observations about the problem even if the solution is not found, which helps the next person to troubleshoot.

You can also do a lot to save others time when you think ahead. If you need to refer to a video, include a timestamp to the relevant bits of your question. If you include 5 objects in the .blend, select the one you have trouble with before you save the upload version so people don’t have to search for it. Or, have the nodes organized and visible in the editor that give you trouble. So on and forth.

You will receive answers instead of guesses or crickets when you treat posting on the support forum like a place for collaborative troubleshooting, instead of going to a repair shop with a picture of your car and asking the mechanic why it doesn’t work.

Note that you can also add:
&t=3m2s
to a youtube link instead of translating into seconds (at least my player doesn’t show seconds only).
