reiss-studio: Thanks for the suggestions - as I said several times above, I used the default PRODUCTION settings for most these images, but tried many others - in ALL cases the texture filter was OFF because I know that it blurs images, but it appears that the images are being unduly blurred even when the filter is OFF. Post filter size was set to 1 (the lowest setting for high detail) In addition I have tried several settings for pixel shading rate all the way down to 0.2 AND 0.1 (this image is the 0.1 setting which is indistinguishable from the 0.2 or the 0.5 settings with regard to the textures themselves. As far as I can see there is no control for "texture smoothing" - there is "polygon smoothing" but that has nothing to do with UV textures. there is "texture filter" but that is OFF by default, so Im not sure what you mean by texture smoothing other than the effect of pixel shading. Since this image was rendered with 0.1 pixel shading (which means 10 samples per pixel) that should surely be more than enough for razor sharp details - yet it has no effect. Once again, I would ask ANYONE who can show an example of sharp and crisp texture detail in a Firefly render to PLEASE do so (and explain how it was done) - anything else is just speculation and has little merit.
