In this tutorial I’m using
Here is what you have to do
- Make a folder where you can save all your “home-made” textures in and make sure it’s organized for easier future access.
- Save your texture images in their folders (preferably high quality clear pictures for better results).
- Open your texture image in an editing program, turn it greyscale either by converting it to ‘Black and White’ or adjusting the ‘Saturation’, then ‘Save As’ and give it a new name in the same folder as the original image.
- Using the original image again, turn it into a negative and then save it in the same folder but with a different name (so now you’ll have three different images of the same material).
- Repeat the process for all the required materials.
- In SketchUp, use random colors or materials and apply them to places you want to add those textures to, then rename each in the Material window to recognize them.
- In The Material Window click the ‘Create New Material’ button.
- A window will open. Click the ‘Browse’ icon, navigate to your material and choose the original texture image, then rename it for easier access later.
- You will find that the chosen material has replaced the original one.
- Sometimes there are extra materials in your model that come from importing Components or simply a leftover from the 2D human figure that appears when you start Sketchup.
- To Clear them out go to ‘Window’ menu and select ‘Model Info’.
- Find ‘Statistics’ and then click ‘Purge Unused’, wait till it’s done then close the window.
- If you have the ‘In Model’ materials shown, you will see that only the materials actually used in your model are there and nothing else.
- In the Vray toolbar click ‘M’ to open the material editor.
- Find the first material you want to replace in the materials list and click it once (Select/Highlight it). You will see multiple tabs, and no preview available or a distorted material image. We need the ‘Maps’ tab for now. Check the ‘Bump’ box (the ‘Displacement‘ box should be checked only if you made that Negative texture).
- Click on ‘M’ beside the check box to open the window and choose your bump texture.
- When you click it, a window will appear with a Drop Down menu under the Preview.
- Choose ‘TextBitmap’ from the browse button ‘…’ next to ‘File’.
- Pick the black and white image.
- After you’re done you will see that your material changes shape and took on a realistic look in the Preview.
- Repeat the last few steps to all your materials. It’s a long process, I know, but it’s worth it since you get to save that material and use it later!
- Right click your material in the ‘Material List’.
- Select ‘Save Material’.
- Navigate to your textures folders.
- Save it next to its sister texture images.
- After you are done, render your image and see the epic result; you will notice in the render below that the stones look more realistic in comparison to the grass and the cement top & base.
