Difficulty editting textures

I am experimenting with displacement textures.

After reviewing the rendered results, I try to re-edit the texture by adjusting my last texture values. I go into the material editor, either clicking on the material in the render window or using the material editor in the SU model, then go to the advanced editor (the only way to get to the displacement texture and values). I have to click on the texture maps tab and then the texture to get the displacement settings displayed. The scale and bump values are reset to the defaults, not the last values. This makes adjusting displacement textures very slow and difficult.

Using bump and scale

I use the Advanced Editor to see the 3D view of the texture as I make my first adjustments. After a rendering, I can go to the Editor (NOT in Advanced mode) and the last bump and scale values are displayed. If I go back to the Advanced Editor to see the 3D view again, and click a texture pattern off and on to get the scale and bump levels displayed,the scale values are different from the Material Editor values. Example: a scale of 300 becomes 7600 on the advanced editor. How can I do simple scale and bump adjustments with the 3D view displayed?

I believe that the difficulty that you are having with displacement is caused by the difference between using the SketchUp materials and the Materials placed from the AccuRender nXt library. We remember where the original texture came from, and we try to reuse the SketchUp settings, for users who do most of their editing with the SketchUp Material dialog.

So, when you start with a SketchUp material with a texture, we always remake the first texture in the nXt material for the rendering from the SketchUp Material texture, so any changes made on our Advanced Material Editor for the texture will be lost. We use the SketchUp Texture Image and size specified for that texture to make a new Texture image for nXt material.

The nXt material can have a total of 4 texture images, so you can add other images to use for masking and displacement, but the the first texture image will always be remade using the SketchUp material.

However, if you place a material from the nXt library, then you can edit all four available texture images in the Advanced editor. If you want to use Displacement, use one of the four available texture images for the coloring and bump, and another for the displacement. You can use the same image for both, but one would have it "map Type" set to be a "Standard" image, and the other would be set to use to Displacement.

The scale shown on the nXt Advanced Material dialog is in Millimeters. All of the setting on the AccuRender dialogs are shown in metric.

They did recently add a setting to that dialog to show the units in inches or millimeters, and that did work for a while, but it looks like it's not working anymore.
