Issues with object rendering in Rendered Texture

Unity Engine
1

This is a wierd one. My client has come back to me with some issues with the objects being displayed in a window getting all corrupt. See attached.

This model is streamed in from the web server as an AssetBundle, then displayed in a RenderTexture over the GUI. Now, this works perfectly on my Mac, and Windows 7 machines, etc. Basically, everywhere I’ve tested it, it works.

I’m not quite sure what’s going on with my clients system. But I suspect it’s a gfx driver issue, or something to do with the fact he’s running in Windows XP (on his laptop!). This is now a Unity 4 version of the app (Was also happening in the older Unity 3.5 version).

So, my question is, has anyone else ever experienced this issue in the past? I guess I’m just looking for clues as to why it might be happening, as I’m a little stuck!

In summary:

  • It’s running as a Web Player.
  • He’s tested it in Firefox.
  • Running Windows XP on a Laptop.
  • I’ve asked for more information (make/model of laptop).
  • I’ve also asked him to clear not only his browser cache, but also the Unity Player cache.
  • I’ve asked him to run it in Chrome, although I suspect it will make no difference.
  • I have asked him to update any gfx drivers.

Not sure if it’s just me but I can’t see the attached image.

Oh. very strange. Working from here. But here’s the link to the image, just in case

Got it, had to clear my browser history.

I reckon it’s a shader issue, have you tried simplifying the shader?

Well, the shader is just a simple Diffuse shader. This issue only appears to be happening on my clients Windows XP system, and only on these models that appear on this render texture. The models in the environment all work perfectly on the same system.

Ok, you could try pumping out the render texture to a png to see if the problem stills exists and it’s not frame by frame issue.

Will be interesting to see what Unity has to recommend for this one…

Sorry to be a bit thick, but not sure how I’d do that.

Actually, the problem I have with this is that I can’t recreate it on any of my test systems. So, any changes I make, I have to upload and wait for an answer from the client. Pain in the bum! I might actually install Windows XP in Parallels to try out, but I doubt that will help :frowning:

Ah! ReadPixels. :slight_smile: Sorry, I was being thick…
