Material Setup and File Organization Questions

I am a new user, but I have tried to read all the dosumentation prior to asking my questions. So if I did miss the answer, I apologize in advance. I realize that we will have large material libraries over a short amount of time, which is a blessing to an architectural designer, I would like to create an organized folder structure for downloaded materials along with my own. Is it as simple as creating a User folder with sub folders for material types such as glass, wood, brick, stone, etc, then placing all of the material zip folders within those and then import? Currently I do not have this folder setup.

I have tried to create new materials for stone using UVMapped textures, I can highlight the mesh within the file tree, the edit a material selecting the appropriate textures, but I do not see a way to save the material when created. This of course means that the material does not show up in the scene. But I can recreate the same process selecting a material from the library, apply it to the mesh and it works correctly. So I am sure that I have just fubared something. I tried for several hours to correct this without success, so I am finally asking for help.

I am trying to recreate this render within Kerky, it was orignally modeled in Rhino and rendered in Flamingo.

Thanks

there's a tutorial on library creation in the Wiki ;)

When I go to that panel, the save button is greyed out. I cannot select it.

I see, need to send to a library first. I missed that line in the help, because it was not there. :?

Okay, got a user library created. Saved the first texture I want to use, which contains a single color map 8192x8192, and a bump 8192x8192. I select the mesh and apply the material to it. No problems, but it does not show up in a render. I then select the material library namer user, at which point Kerky crashes. Is the texture too large, other thoughts?

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

I don't know exactly what you are trying to accomplish, but in my humble 10yrs experience very hi res mats are only needed for very close up shots. In most cases, your images for mats want to be as small as possible to cut down on memory usage and render times. I downloaded hi-res images for my wood floor from arroway.de, you can see it in the materials section of this forum. Then I halved the size of them, because I felt I didn't need them that hi-res. I don't typically take pictures with my cam lying on the floor, so I have had no probs with my low-res mats. my advice: make a mat with the same mat shrunk down by half or by .75 and see if it renders. if so, there's your answer.

how are you suggesting that you are shrinking your material down? why should it not tile if it were larger and all of a sudden start tiling when it's smaller?

I don't have this issue, so please be patient with me.

I wasn't talking about the tiling, I meant to reduce the size of the texture which would reduce the total file size. This would cause less load on the total Ram used, which appears to be causing my problem. The material panels are responding sluggishly when selected, I forgot that the stone textures I used originally were setup for very detailed rendering, and they are quite large in pixel size, and quite large in megabytes. Sorry for the confusion.
