Displacement maps - rendering white
Hi, when I render with the displacement map for the fabric, there is no image anymore after rendering. The fabric is an Xtex file and I add the displacement map associated with this file.
When I remove the displacement map, the rendering works perfect but I prefer to have the displacement map for more dept in the threads of my fabrics. what can be the solution?

thank you ottoline
I create textiles in Kaledo weave, for my research the parameters of the threads (diameter, twists, TEX, ...) and weave need to be exact. The threads have often a diamter of 0.30mm and the structure of the thread should be seen, when zooming into it. Because the file of Kaledo .kwd is not compatible with CLO I export them as.png and then make the maps in Xtex. How would you suggest to make the maps for CLO based on my Kaledo files? I tried to upload the Kaledo file, but not possible.

thanks ottoline! Which other softwares do you use for recreating realistic weave? Do they also include the recreation of the yarns and possibilities for tapestry weaving? Do they have the weave software behind for plugging into weave looms?

nathalie,
most weaving software's allow you to scan in your yarn thread sample to create a random length bit file to use as the yarn element. That's pretty standard. You can even do that now using 3D cross sectional sliced data for yarn twist, strays and packing. Each to their own.
I built my own image scanning setup (hardware) as it is unlike anything else technically available. It uses an entirely new process for image texture capture. And it works at amazing speed. It takes me a few seconds to generate a fabric texture set of maps, as my process is hooked into my hardware. I also have a unique mounting system as It doesn't require a human to mount the fabrics, so that speeds up the churn rate to thousands of fabric textures per day. I don't provide textures outside of what I immediately do for my specific area of photo-real garments.
I have taken a completely different approach to creating synthetic fabrics and that certainly works well for what I do in CG.

it sounds amazing! I have the problem with certain textiles who have dimensions of 1.5m/ 2.5m to scan them. They have all different types of tapestry, no repeat.. can you scan these kind of fabrics?

If they are large you would need to either use a scanner to cope with that size or make a custom bit of hardware. Depends what resolution you need the image to be for the final texture as to how you approach the problem. The best large format scanner I have used is for historic costume capture. I used it for a museum based Egyptian CG garment project I had. Best large format scanner on the planet > https://crusescanner.com/hybrid-3d/
You can get flat bed scanning done in 3D for museum textiles, that has been around for some time. And there are bureau's that specialize in that if only a few items. If you are doing that frequently you have two choices - make your own hardware, or buy in the existing hardware for large format acquisition. The artworld and archeology world use this scale of hardware. Have you checked out those channels ? > https://www.metis-group.com/product/surf-3d
Vizoo created a newer larger format scanner that can take A2 image captures. >> click link

indeed I can imagine that the costs can add up... my projects are all research projects in a university or museum context. We need real high-quality images that can be imported in CLO, from both front and back with the tiniest details possible. I'm thinking of developing a hardware capture device for these large textiles, how would you do this? What kind of budget would be associated? Costs should be payed by research funding. Costs should be covered by R&D budgets
I'm in contact with Vizoo, as we used their scanner already for small projects. They told me about the A2 but for a lot of the textiles this is still too small. I looked into the following flatbed scanner: https://www.sma-edocument.com/products/Products/2/versascan-4870-flatbed-scanner.html
