Can someone please tell me what this means: Source map for render target MC_1.dds cannot be a DXTn format.
Thanks

Try 8888?
possibly cube/normal map?
It would help to know what sim/what object this is for.

Pants is right.

The error is telling you that you can't use a compressed texture (DXT is a type of compression, like jpg, but specific to dds). In rFactor, this error comes up for textures that are render targets (like mirrors, gauge faces, etc), and for bumpmaps. It may show up for other textures, but I'm not certain which ones off hand (no time to dig through stuff right now).

If it is a mirror or gauge face texture, just use a .bmp format if you don't need the alpha channel, or .tga if you do need the alpha channel (for chroma transparency or such). If it's a bumpmap, I've had good experience using the 5,5,5,1 format in dds. This gives enough color depth to the RGB channels for the bumpmap to work well (4,4,4,4 is just too stepped), and 5,5,5,1 keeps the file size much smaller than 8,8,8,8. If your bumpmap has very subtle changes in it, then you'll need to use 8,8,8,8.

I'm having the same issue with the Mirror.DDSand gauges texture (Velotroll.dds). Tried to convert to BMP (the correct format for mirror) and TGA (for Velotroll), but game still showing DDS for both.
