Send in your c4d scene file with the jsplacement map, I'll set it up and send it back but anyways it works just like a displacement map would.

hi, I appreciate it a lot thanks man I've send it to you on. your email xebajac@zdfpost.net idk if that's it. also I did try setting it through the Arnold displacement directly but it doesn't give as much detail.

thanks a lot again

Check it out and play with the settings especially in the Arnold tag displacement and subdivision, just give me feedback.... https://ufile.io/scf7um8a

thanks alot it helped but also realized the effect I am looking for involves me turning the Subdiv Iterations to 9 and I doubt my laptop would be able o take that

this is what I was looking for, you know of any other way of getting something like this ?

Have you tried enabling autobump so that you can get by with fewer subdiv iterations?

I guess you should just put the max subdivisions your system can handle.... We'll have to call on @lee griggs to know if there is any workaround.

Yes, I enabled autobump in the test scene uploaded @thiago

What happens when you use 9 subdivisions? Does 8 work? Maybe you shrinking the size of the map would help. It is being converted to .tx right?

lee Gregg 🙂

yes it converts to .tx unfortunately even a 6 is to much for me to see on my ip I waited 36 min to just get a preview of a grainy render.

I am trying to see if there is another way to get such Sci Fi texture if you know any I don't mind researching and learning another way.

thanks a lot

Something to consider anytime you're relying on displacement for fine detail (especially JSplacement) - be sure that your mesh is tessellated enough to begin with. In other words... you'll need a nice distribution of polygons and/or triangles across the surface that you plan to displace. You'll still probably need to add render-time subdivisions, but IMHO it's good to start with an already reasonably dense mesh and rely less on super high subdivision settings. It all depends on how much you're trying to manage scene interactivity and render wait times.
