R8 image problem

[ashwin.sudhir]

We programmatically create an image that we upload to the GPU very often. To reduce the stall we'd want to keep the image size as small as possible and hence chose the R8 format.

When we create a 146x146 sized image we get a strange problem.

 

The image looks fine in this preview

 

But when we see it in the material preview (the eye icon on the diffuse texture), we find it is distorted

 

And this is how it comes up in the game too (distorted).

 

Strangely this doesn't happen when we create an image of double this size (292x292). We wouldn't want to do that though, as the stall becomes more obvious.

There were several fixes regarding texture loading. I think this problem will be solved with the next SDK. What graphical API do you use?

These are the APIs we use</div>

C++

=======

 

Unigine::ImagePtr m_pImgFoW;
...
memcpy_s(m_pImgFoW->getPixels2D(), nBytes, m_pBufferR8Downscaled, nBytes);
m_pImgFoW->blur(1);
#ifdef _DEBUG
 m_pImgFoW->save("FoW.tga");
#endif

 

In unigine script

==============

Material mat = engine.materials.findMaterial("mesh_terrain_base");
int idTex  = mat.findTexture("fow");

mat.setImageTextureImage(idTex, img);

Please, wait for the next SDK, the problem seems to be fixed.

Thanks manguste ;)
