When laying out a texture on a UV snapshot in Photoshop (or your image manipulation software of choice), does exporting as one of the above mentioned files, make a lot of difference when applying the texture to your model in Maya.
I never used to have any problems applying a TIFF. image, but in 2011, it seems to make it translucent, but TGA. works fine, does anyone experience anything similar?
Don't have 11 yet, but does your TIF have an alpha channel? If you plug in an image with an alpha channel as Colour, it will automatically assign the alpha channel to Transparency as well.
ReplyDeleteTo delete an alpha channel select 'Window' then 'Channels' in Photoshop, then drag the alpha layer into the bin.
Sorry if you already knew this, that's the only solution I could think of.
Yes it makes a huge difference. .Tiff and .Tga carry a huge amount of information (too much in some cases) but have the benefit of housing 'alpha' channels alongside colour. These are used to control transparency in Maya etc. Png, Jpeg are low quality and predominantly for the web.
ReplyDeleteSo, either .Tiff (with no compression) or .Tga (Targa) files are fine for most 3d applications. However what makes a great difference in Maya is to turn off the 'filter' on the image node in maya. This function blurs the image so by switching it off your texture will appear sharp.
thanks Simon, I normally get on fine, just delete the alpha channel and it works, but this time round it didn't work with Tiff. however literally just exporting it as a Tga. and reapplying it was a quick solution.
ReplyDeleteAnd also thanks Alan, never really used textures to great effect before, so am still learning in that respect, and was unfamiliar with the 'Filter' on the image node. Will, try that with the next texture I apply in Tiff.
thanks guys!
