Multible, indepentent displacement maps in one texture

[germannick]

I need your clever ideas for my problem.

in the attached image you will find the left pipe welded onto a floor sheet. The weld is created with a displacement map. I would like to add a second and complettly indipendent displacement map onto the right pipe. I like to avoid using seperate geomertries for it, beccause the final texture needs to have a contineous worn appeal and no visual breaks (it will be used in an animation and not as a still image where I could retouch it).

Thank you in advance

Do you need to be able to control both displacement maps? If it's just a matter of setting both up (and you won't need to come back and change anything later), you can create a "baked" displacement. I learned this neat trick from Eric (bdesign).

Start by applying one displacement map to the geometry, then export the part as an .obj (.stl should work too). Import that file into your scene and apply the second displacement map. Of course the downside to this is that you can't edit the initial displacement. So until we can actually bake displacement or have multiple displacement nodes, this is the only way I know of. Hope it helps!

Don't have anything to add here that would help as I really think Eric gave you your best and only solution. Just wanted to say, those welds look really good.

Have you seen this video on weld seams ?

I am going to try this tomorrow, I didn't know this was possible at all! That's so cool and useful to know, thanks Eric for sharing!

Hi Eric,

thank you for your feedback. That was my work around within Rhino. I did not think to use this method in Keyshot instead (works much faster) I'll follow your suggestion forward!!!

Hi TGS808 , thank you for your compliment. It took me a few tries to create this seamless texture to create this displacement map (Illustrator was a better helper than Photoshop this time)

hello germannick,
generally a good job, I'm sorry to say that but the welding seams are unfortunately wrong, as an welder wich such seams, I woud lose my job,
but If you can tell me what type of welding it should be and what material it is, I can help you with the right seams.

There is a Keyshot quick tip on combining displacement maps: https://youtu.be/I39MB5T5opA

Hi Morgan,
any hints and clues are very welcome. Thank you for your offer!!! Its my first "welding" experience, and not only on Keyshot.
Here are two images that I recieved from my client as reference of their material and color. Also the welding lines are visible. You can tell, I already cleaned them up a bit because they seems really rugged.

Sorry for the late response but I was on the way.
Here are pictures with correct tee joint pipe weldings.
I hope I could help and I am happy to answer any further questions.

for what it is worth,
Magnus Skogsfjord nailed it pretty much on the head...
