Tileable Maps Photoshop 3 Layer

²Digitalgames

Hello,

i wanted to ask if you have a good idea how to make photos in Photoshop tileable, if you already have normalmap and also ambientocclusion baked out from a photoscan.

I know how to do it with one Layer, but how can i repair and clean up seams with multile layers ? I can share the results for DDO Materials if its working.

Thanks in Advance

Succes- Tried with Layer to groups ,duplicate first group , offset by half of the pixel with every layer in the second group and use masking to make it tileable .


If someone is interested in more let me know.
Would be interested in other methods !

Yeah if you already have the other maps, then you need to tile them exactly the same way. So using the same offset values, and same layer masks, probably the best way. Out of curiosity, what did your layer mask look like? A smooth gradient, or a blotchy edge, or ?

My new test : Not sharp enough but its all about testing around. :poly121:

For some reason I cant see the attached pictures you posted, probably looks awesome!!:)

A small tip I usually do when it comes to using tileable photoscanned data of ground surfaces etc, or any surface that are not pattern specific. I make four duplicates of each layer group (diffuse, normal etc) and rotate one group 180 degrees, next group 90 cw and another 90ccw. For the 90 degrees I use a channel mixer to correct my normal map. That way I have some more variations pieces to play with for my final tileable texture.

Hmmm i don´t know why that is. Nice ideas ! Never thought about inverting R or G in an Normalmap texture to get it rotated. Neat

yes it can be pretty useful.

180 deg: invert red and green channel in texture

90 deg CW: invert red channel in texture and use channel mixer to switch place of red and green channels

90 deg CCW: invert green channel in texture and use channel mixer to switch place of red and green channels

Photoscan + DDO + 3DO





Edit: Combined new material :



So how do i share this material with DDO users ? (If you want it)


Thanks BMC131 !

Hmm, the offset trick is introducing a lot more repeats to your texture. That big stone in the middle is noticeably repeating in a diamond pattern. You may want to re-think this approach.

I find it works better to severely limit the width of the mask, so I'm only pulling in enough of the offset layers to hide the seam, and no more.

Here's how to export DDO materials.

When on the subject making tileable textures, the Photoshop filter High Pass(Other-category) can be useful at time to removing big scale things that catches your eye when tiled.

Amen to that brother. A good tutorial about it:
