CAD Rendering options I found last night

I use Blenderkit usually to find a free material close to what I want and then edit from there.

That one is a procedural shader. I think its called “printed plastic” or something, then you just need to scale and/or rotate the pattern to get your layers how you want

It has some free HDRIs as well, so I usually find one of those for a starter lighting setup, then edit the scene around with 3 point lights and walls, etc depending on what I want it to look like

okay I have been playing with that exact setup.

I can’t get copies to rotate a different way, I can get different colors though. I have one more idea to try but that node stuff is very new.

you mean to get your layer lines to be different orientations on different objects?

Yeah. I can rotate and scale them. make copies of the texture and add it to different parts, and change the color but if I rotate them they all rotate.

if you rotate a texture all of the textures rotate?

Or you talking about the geometry?

hard to explain

they are named different things, I can change color and scale independently, just not rotation. I am guessing color and scale are on the first setting page and rotation is three clicks deep.

Man, I remember when rhino was a free alpha.

You need to check the direction of the normals in blender, “flip normals”, and then “uv-unwrap” the parts.

It’s not an image texture

Sorry, I got real busy yesterday, and I’m out of town today. I think I have a file where I rotated this. maybe in the printer one? I’ll try to check tomorrow if you don’t get it by then.

You’ll need to make changes in the Shading tab in the node editor most likely

You’ll also want to make sure all of your transforms are applied to your object.

Ctrl+A then “All transforms”

Unapplied transforms can do some weird things

I did ctrl a, I had to do items one at a time. if I selected the entire lr4 it did not like it. didn’t help.


for this texture, I copied it, made a new one, unlinked it, single user. that all seems to work for the surface level controls, but the one to rotate is three levels deep. That is what I am trying to show with this screenshot. green arrow is the texture, rotate is two clicks deeper. The texture creator says in the description this is how to rotate it.

I tried copying and duplicating that module(?) reconnecting, still changed them all.

I feel like I am doing all the right things for other textures but something about how this one is made is not doing what any of the google searches say.

my next hope is maybe to add a surface level rotate instead of the bands XYZ thing. or just find a different texture.

wait, I got it somehow.

My goodness that was nuts.

so the green arrow used to have a linked number here like the orange one.

I had to go through all my copied…and unlinked… materials and clear out the links in this section. I kinda understand why, but if you copy a material I really think the default should be unlinked everything and if you need something linked you go in and add it. But that is coming from someone with zero blender experience.

Also guilty of being a Sculptura user, prior to its renaming.

Mike…you are right again. Blender is worth figuring out. I am sure every time it is going to be a pain to figure things out, but you can really get in there and do anything. For better or worse.

Finallyyyyyyy getting somewhere.

If anyone wants to play with this file, I think I can share it.

Now I think I need to get in and tweak each texture to make them look more real but it is the best I have gotten in blender to date.

Pretty fun for a backdrop. I can see now I need to rotate it a bit more so there is more LR and less table but Peter I really like it.

Any suggestions?

Are you using EEVEE or Cycles?

I can’t tell for sure on my phone, but looks like EEVEE.

If you want realism, switch to Cycles

Once you do, the lighting will probably look dim.

You’ll need better lighting for cycles, but you’ll get realistic textures, shadows, light bounces, etc

There’s an add in somewhere that can get you single click 3-point lighting.

I made my own funky lighting so that could be it.
