Kerkythea: How do I apply Mapping to a Group?
-
I posted this over on Kerkythea's forum, but haven't got a response so i thought i'd put on here too.
My question is how to apply a bump map to about 250 different objects at the same time. I've tried to group them and edit the group, but that doesn't work. I've found this thread- viewtopic.php?f=6&t=8044&p=69600&hilit=group+material+edit+material+group#p69600 , but the instructions don't seem to make sense. I'm not sure if the newer version has changed things or what. I model and render landscape construction projects for sales and production.
Here is my workflow:
-model a paver patio
-use a couple different plugins to get my header course in place
-the header course are all individual faces
-use the paver texture and adjust to fit a within the bounds of a header paver
-copy UV coordinates and paste them into all other header faces
-when i export to kerkythea, i have to change the settings to- Geometry(yes), Lights(yes), Clay(no), Photomatched(yes), Default UVs(yes), Instanced(no). I had to play around with the last three settings in order to get my border pavers to show up correctly in my render.From what i gathered, when Photomatched is on (yes), it imports the header pavers into kerkythea as individual materials. I can group all of them into one group, but when I try to edit the group, it won't allow me to add a bump map. My question is how can i apply one bump map to all of the different textures without doing it to each individual material?
Any help is much appreciated!

P.S. I can upload a photo if that helps.

yes, some screenshots could help. I read your request also on KT forum, but I still cannot catch what you're trying to achieve... surely you cannot add a bumpmap on more than one materials

Here is some exports and renders
This is what it looks like in sketchup
This is a render with photomatching turned off. All of the header is one material.
This is a render with photomatching turned on. Now, all the header are separate materials.
I can't afford the time to apply a similar bump map to each header piece. Maybe i'm being ignorant, but it would seem as if this is a big enough problem that i'd consider changing render programs to fix it.
Any comments or opinions would be appreciated.

I must be slow today...all this stuff have no much sense to me, if you're using a textured material (not a simply imported image) photomatch shouldn't affect at all the exporting. You adjusted uv mapping on each face (did you?) so you should have just one material, choose "no" on the request "default UVs" and in KT use UV mapping. Also check if there are backface materials applied
-
...In any case the solution is mapping and exporting correctly a single texture, apply a lot of bump maps is a quite awful workaround
-
I am applying a texture to one header piece, adjusting it to fit within the bounds of the paver, then copy and pasting the UV coordinates into all the other header pieces. Is there a step i'm missing?

Why don't you try quadface tools? I saw that plugin solve a similar problem in an armchair, though I don't know if it was rendered after...
Also, have you tried different mapping options inside Kerkythea? It seems to me that if you set one material only (without photomatch turned on) you could easily tweek the UV cilindrical map in KT to get the right effect.

I think QuadFace tool is the one to use with this kind of UV mapping. Why not to post a .skp... sorry, cannot quite follow your workflow.

I'm sorry I'm fairly new at this. This is is my workflow (many thanks to Adam!)

Everything works great except for the small problem of editing the mapping within Kerkythea. Should I be using a different render program?

With a quick look your texturing tehnigue is probably the first thing to be fixed. I think the way you texture creates skeeved textures... definetly a not good news for most renderers. I think there is reasonable good texturing tutorias using quadface tool available even here inthe forums. Sorry no link (a bit hurry to search it for you), perhaps someone has a pointer to that tutorial... I'd sart with creating a suitable texture for hardscape border with PS or some other editor, not by stretchin and fitting texture in SU.
If you want to use some other renderer, pick one than can handle skeeved textures.

Thanks, I'll check into it.
