Resizing Textures with Bryce

Introduction

For sure you have had textured an object in the past and you were not happy with the size of your selected texture. It seems to be too rough or too fine and does not really fit into your picture. This tutorial will help you to adjust your textures in their granularity.

Step 1 - Texture Your Object

For my example I created a box and textured it with the standard Gilded Cage out of the Wild&Fun materials.

Step 2 - Check Your Render Output

My render looks now like this.

I'm not happy with the size of the grid. I want to have it much smaller.

Step 3 - Open the "Edit Texture" dialog

Enter the Materials Lab again and click on the small greenish button on the top left corner above your texture display.

A small 'Edit Texture' window opens.

In this small window you can change the size of your texture with the first three parameters. With the additional parameters you can ajust the position of the texture, it is worth it to try it out but this is not content of this tutorial.

We concentrate on the first three parameters. As you see, in my example all three values are set to 37, 5%.

0% means the texture is as large as possible.

Higher values define how often the texture is repeated.

Negative numbers don't make the texture larger. See step 6 for how this works.

Step 4 - Define New Percentage Values

With a click on a percentage value, you will get a small input field, where you can define your new percentage. Have a look at the small preview window in the Materials Lab. There you will get a rough idea of how your texture will change.

This example shows the change of the X axis to 120%. Y and Z remain on 37, 5%.

Here I changed the Y axis to 120% and the X axis back to 37, 5.

Step 5 - The Final Values

And here is my final render that shows the result with all axis on 120%.

Funny, isnt't it?

Step 6 - Negative Values

Negative values will also increase the frequency of the texture, but in the different direction of the axis. Here an example with a sphere.

In this example I used the Texture Alien Tree Bark out of the Wild&Fun textures. The standard values for X, Y and Z were all 25%.

Now I changed all values to -25%. You will now notice that the texture flips somehow on all axis and looks a little bit strange. So be careful to change to negative values.

Try it out yourself with single values.

Step 7 - Adjusting Trunk Materials of Trees

The resize option for textures is very helpful for tree trunks. If you create a tree and you change the trunk thickness you mostly have to change the texture size to fit it.

For this tree I used the default Silver Maple and changed the trunk thickness from 40 to 87.

The render result does not really look like a real trunk.

Now we have to change all the texture axis values in the same manner. This means if you double a value for the X axis, you have to do that with all other values as well.

In this case I multiplied all values by 20 and this is the result. The bark looks now more realistic.
