Model appears black

[worsas]

Hello.

I've downloaded the compiled 1.0.0.rc7 - version for windows.
When I use the application, the mesh appears completely black, which makes it difficult to properly work with it.

I'm using Windows 10
GPU: Radeon RX 570 Series

I hope, it can be helped.

Hi @worsas are you able to open this example file: https://dust3d.org/model-complete/examples/banana.ds3 ? Or could you provide your model file?

[worsas]

Hello again.

Yes, I'm able to open the banana.ds3 file just fine, but the model appears black in it aswell. It doesn't seem to have to do with any particular file. When I create a new file, the model is black. When I open an existing file, it's the same.

I've just switched to a new PC with Windows 11 and "installed" the same pre-compiled program and it's exactly the same thing as in Windows 10. However, I'm using the same graphics card, which I had in my previous PC with up-to-date drivers.

I'm including the file seen in the screenshot above, just in case:
HorseTest.zip

Thanks @worsas I tried your model on my machine, it renders fine, so it should be issue related with OpenGL environment. If possible could you provide the debug info(Menu -> Window -> Debug -> Select All -> Copy) and version info(Menu -> About -> Select All -> Copy).

Thanks for the quick reply. Here is the requested output (I did open the Horsetest.ds3 in that session):

@worsas Is there a graphics processer control panel which you can select integrated graphics for specified application? If so you can force it to use integrated graphics for Dust3D. Sorry, I don't have Radeon RX 570 Series to debug this issue at the moment.

[worsas]

That's fine.

I just tested the app on a different windows pc with a Geforce GTX 960M and there the model appears fine.
So it seems to be related to the Radeon Graphics Card indeed.

[Dhelio]

I can confirm that. On my desktop with a 6800xt the model is all black, while on my laptop with an RTX 3060 it is viewed correctly.

[luzpaz]

So this is a Graphics card issue ?

[Dhelio]

@luzpaz Pretty much. Until the rendering is fixed there's little we can do, I guess.
