Problem saving Photoshop files

NAIMA

Hello I am trying to save photoshop files in the dds format or crytif format , but whenever I go to save in crytiff format I get this error ...

while if I save as DDS format with the nvidia dds plugin the colors are washed out after I open again the image as also can be seen in the previouse picture , that sand was actually gray and not as white ....

I dont understand what I am doing wrong If I have theimage in 32 bits I cant use filters onit .... also the normals get washed out and look less dense andstrong ingame , how can I fix this saving problems?

You are using 32 bits per channel (bpc) instead of 32 bits per pixel (bpp). 32bpc color depth is usually only for HDR imaging, games mostly don't support it.

To fix it, go to the Image menu, Mode flyout, and choose 8 Bits/Channel. 8 red + 8 green + 8 blue + 8 alpha = 32bpp.

My original files are tga and are already 8bit per channel but when I save in DDS format DXT 1 they become 32 bit per vhannle and are washed out ....

Sounds bizarre. I can't verify since I don't use CS4. Do you have the latest NVIDIA dds plugin installed?

If it still happens, you could try searching and/or posting on the NVIDIA developer forum.

Also another problem I am having is how I can make a decent bump/normal in order to give the right feel of up and down little dunes of sand? So far this is the best effect I coul dget but It fees flat .....

I think this ^^ belongs in the other thread.

I still get the feeling your TGA was in 32bpc mode before you went to save the DDS.
