Decal/Texture instances do not render on TrussPart instances

Problem

I was trying to apply a Texture to a TrussPart and it’s not working. I know the image is valid because the decal can be used as a MaterialVariant and it works.

The API documentation for the truss part and the texture do not state that it cannot be used like this. In fact, the documentation for the texture instance states that it will apply the image to the BasePart it’s parented to. I checked the documentation and TrussPart is a descendant of BasePart so that shouldn’t be an issue.

EDIT:

On a hunch, I tried a Decal but that didn’t work either. Like Texture, the documentation for Decal also says that it can be applied to a BasePart. I wish to reiterate the fact that none of the documentation mentions that Decal or Texture cannot be used with TrussPart.

As for plugins, I have a bunch that are installed, but very few are enabled. The ones that are enabled are listed below with links to their details page on the Roblox store website:


Expectations

What I expect to happen is that when I apply a texture to a truss part, the texture is rendered.

A bare baseplate that shows the problem as well.


Reproduction

To reproduce the issue, perform the following steps:

  1. Open the attached baseplate file in Studio.
  2. Observe the issue.

Files

Engine - Texture on Truss.rbxl (54.4 KB)

Until they fix it, I would try making a truss MeshPart in Blender or smth and then importing it to Studio. Don’t know if the climb-ability would be the same, but it’s work a shot until they finally fix this.

Hello,

We currently don’t support decals on TrussParts. Please feel free to post this as a Feature Request :slight_smile:

Best,
