How to fix Displacement Map Issues on Hard Edges?

[Terryvfx]

Oh you! I know what you are saying haha maybe you could release that specific tool outside the whole Acquitecture package as a plug or something and well the Rock it's just a procedural by default it doesn't have UV's but I found out that Cinema4D can make UV's automatically that Octane can read using the mapping section in the material I choose box mapping and as you would expect I have flying polys in the seems of the UV's but then again the Cinema4D default displacement just works...

here is the rock in case you want to take a look at it: https://drive.google.com/file/d/0B-YugS ... sp=sharing

Sorry, I'm keeping it within Phantom Architecture, easier to maintain for me, I will also include a bunch of other super helpful tools, this one is just the first, I have a lot of ideas to shave off tons of hours of workflow. I want to provide it as one solid package, in the sense that when you use this you can't go without it... again, gotta put the bread on the table...

So I threw the rock in PA and it worked:



Now I should note that because of the way the model is tessellated, the filesize of the rock has jumped from 7.6 MB to 22.1 MB. But I see the rock model is very detailed, in this case the way I would handle it is use the Decimate function in Blender to get the polycount down, then progress it in PA and get a model that looks great as well as is a bit smaller. When you have great looking displacement, you can cut back on the polycount on models like this

By the way I won't upload the rock OBJ because I want to keep the space on my webspace as compact as possible, but if you send me your e-mail I will send you it through WeTransfer, if you want it

Don't worry the render regarding the rocks already went out of the oven and I guess I will just wait for PA to get released!
PD: the rock looks niceee

Hi all,
Octane uses the Phong angle to determine the orientation of the extrusion of the displacement. With a cube by sample, you should try to use an angle higher than 90° in the Phong tag. For a better result, use a subdivided cube or a flat bevel for a better control of the Phong and Octane's displacement (like in box modelling with a Hypernurbs).
I hope this will be usefull.

Phantom Architecture is available by the way

Hi Niuq Cam,

If you want more informations, i have writen a small article on the subject on my blog (in French).
