How to add a texture image to a sculpture

Artistic Support Materials and Textures
1

Hello everyone! I am VERY VERY new with blender. I’ve kind of just been winging it and doing what I need for the game I’m helping to make on Roblox, which is purely the basics. I have been running into an issue that I can’t find the answer to on the internet- how do I add an image texture to a sculpture? I know how to add image textures regularly, you make a new material and hit the little yellow dot and import an image. For some reason, this is not working on the little mountain I have sculpted. I’ve tried smart UV wrapping, and I can’t manually UV unwrap it because the sculpture

has no faces, it’s a sculpture. Does anyone have any idea how to fix this?

Assuming that your texture image is on the left side and the object you want to apply the texture to is on the right:

Open your object (mesh) for editing. Select all the verts (A) then, from the UV menu, select “Unwrap Angle Based.” You can also just press (U) and select from the menu that pops up.

Go to your UV Editing context (Row of top tabs). You should see a 2-D unwrapped representation of your mesh. (Be sure that your object is still open for editing.) The verts and edges on the UV-unwrapped representation correspond EXACTLY to the verts, edges and faces of your object.

In the menu bar of your UV window, click the “file folder icon” and find the image that you want to map onto your object. It will appear as a layer under your UV Map. You can select, drag and edit the verts of that UV map until they line up the way you want them to. Just do this until things are the way you want them to be.

Go back to your Default Workspace and make a new, blank material then apply it to the object. Judging from the image you posted, I assume that you’ve gotten this far. Yes? :slight_smile:

Now, it’s time to go into your Shading Workspace and hook things all together.

In your Shader Editor you should see a generic layout of your material nodes. There is likely to be a Principled BSDF and an Output node. Again, I’m assuming that you have gotten this far, already, and can find your way around. Right?

Now, it’s time to hook things up! :wink:

  1. Shift-A to ADD a Input > “UV Map” node. Select the UV Map of your object from the drop-down f it isn’t already selected.
  2. Shift-A to ADD a Texture > “Image Texture” node. Use the drop-down to find and select the image texture that you want to apply to your object.
  3. Connect the nodes:
    UV Map [UV] ==> Image Texture [Vector] ==> Image Texture [Color] ==> Principled BSDF [Base Color] ==> Principled BSDF [BSDF] ==> Material Output [Surface].

If all goes well, you should have a basic UV Mapped, Image Texture on your object. This is just the basics. Simply, how to put the texture image onto your object. There’s all kinds of other stuff you can do but this should be enough to get you started.

Let us know how you get along, so far. Once you get the first part down, we can talk you through other things you can do to improve your results. :slight_smile:

Welcome :tada:..

You might do a little research.. it has.. but the are properly too many, so you might try some remeshing.. and for unwrapping → Cylindrical projection with maybe some adjusments along the V-coordinates (scale and move)..

I think you might be right. :slight_smile:

I know that my answer was long and oversimplified. I answered like that, on purpose, because I didn’t know what the OP had done or what he might or might not know. I was hoping to create a baseline to work from.

As I see it, you might be right. There might be too many faces or not enough faces. There might also be enough faces but they are all “twisted up” so to speak, which makes it hard to create a good UV-map. Instructing the OP to do what I suggested was meant to be a way to figure out what’s going wrong.

If the OP had followed those instructions and said, “Okay, I figured it out,” we know what went wrong and the problem is mostly solved. We can, then, move onto finer details and come up with a full solution. If the OP had come back and said, “I tried but everything’s coming out all wonky,” we know what questions to ask in order to help.

I’m sorry if my answer seemed too simple or if it didn’t seem to answer the full question but I thought it better to start out with the basics and work from there. :slight_smile:

Hello!! Thank you sososo much for the response, I assume this is going to be very helpful!! I ran into an issue I’m not sure how to solve at the start: when I try to unwrap it, it gives me the error “unwrap failed to solve 1 of 1 island(s), edge seams may need to be added.” What exactly does this mean and how would I solve it? Thank you!!!

Hi, if this sculpt is high poly it is not suitable for games. you will need to re mesh it.

Usually sculpts are used to get some high level geometry and those details are backed onto some lower lever model as normal map.

So usually you do not unwrap a sculpt.

If you really want to use a very high polygonal sculpt as piece of art or whatever you might even try vertex paint this “directly”. (Which means using millsion of polygons and the need of some high level computer).

In general i think you should state you usecase. Any further tips depends on the context.

You migh also look into some sculpting and/or “adding details via sculpting onto some game asset” tutorials. Maybe even use blender for some “simpler” tasks first to do some practising. :wink:
