Applied Tattoos aren't clean

Why would this be happening all of a sudden, by that I mean I've applied tattoos in the past whether it was in the LIE or simply baked into the texture, and I've never had this problem before. 3rd party tattoos appled in the intended way work fine, but homemade? Not so good.

As you can see the green in the tendrils is bleeding over the outline, the prurple isn't filling the circle, and there's a weird checkerboarding all over the place.

My guess would be too high texture compression.

Try in Render Settings advanced, to increase to threshold values.

That was it thanks, only problem is it chews up the Vram, decisions decisions.

That fixes the issue with my homemade texture, but the lower threshold values aren't an issue with the 3rd party tattoos, they look good despite the lower values. How would I go about getting the same result with my textures?

Don't know.

Which thresholds did you initially have?

And is this applied with LIE?

And can you give an example of a 3rd party where it doesn't happen?

mmoch25

I'm sure, my thresholds in the past were the default lowest settings. Anyway the example below is at the lowest and it looks good.

I think it is the color gradients that effects the compression result.

You have sharp color gradients in your picture. The spider doesn't.

I'm not exactly sure what you mean, do you mean like contrast or saturation? Here's another example.

This is another homemade tattoo, I made ages ago, and it does have that strange bleedin effect. What is there is a part of the design.

felis

In my experience compression will result in bleeding if there is high contrast and different colors within few pixels, i.e. an image with small details.

I think it often might be better with a lower resolution picture that doesn't get compressed.

It never used to be a problem, now for some reason it is, thanks anyway.

That's the common issue with the mode 'Multiplicative Blend'... If you use PNG or TIFF formats with LIE - Alpha Channel Blend, the tattoo's quality will be much better.

I've always done this, and always with jpegs, and it never used to be a problem, as the tattoo on the foot shows. It doesn't matter if I'm using LIE or not. Both the original image and the foot tattoo are baked directly onto the torso/leg images.

This is basic texturing 101. Half of the DAZ store is textures you download and apply. A lot of skin textures come with the option of applying tattoos,scars,makeup etc. what I'm doing is no different, mine just look like someone can't colour in neatly.

My source textures are 4K, the end result is 4K, the threshold values have been the same (512 - 1024) since first installing DAZ years ago. Nothing else has changed. Maybe I need to start looking outside of DAZ.
