| How much does an image effect the size of a Bryce file? In this portion of the tutorial we will examine this. To make the file size change easily seen, I will use a very large image file of 1295 kilobytes (1.295 megs), JPEG format, 2557 x 1726 pixels in size. |
| The graph below indicates the use of the above JPEG as an image texture. Notice that it is not the number of times the image is used, it is the actual application of the image the first time that dramatically increases file size. |
 |
| Why did the file jump from slightly over 100 kilo to 13 megs when we used only a 1 meg image? Bryce does not care if the image is compressed. An uncompressed 24 bit image at the above resolution will be 12.6 megs alone. Bryce does NOT use compression when interpreting the image as a texture...remember that when you use your image textures! These things eat RAM and increase file size dramatically per image! |
| You can, of course, save the picture
materials you make to your preset library. However, as illustrated above these
material files could be very large. One thing to keep in mind about saving all those
neat little presets in Bryce is that you are taking a very big chance of losing them if
you have too many. Bryce loads all of the presets into memory when it opens (not a
good design), if you run out of RAM...it will simply not open the presets and you could
lose them. This applies to all presets, not only materials, but objects and skies as well. I can't count the times that people have posted messages pleading for a way to get their presets back because of the mistake of saving everything to presets. |
|
| I personally don't have that many
presets. #1. I save a Bryce file with the objects, sky, or materials within. When I want one of them back, I open the file and TEMPORARILY add this to the presets, then I remove it when I'm done. Better safe than sorry. |
|
| Now if I want my picture textures back, I simply open the Bryce file and there they are ready for me to use the specific ones I want. |  |
| #2 I save export them and import them back later. | |
| Now that you know all this stuff, go get some really superb image textures and use them in your images. | |

| To make the whole image appear without any alpha effects... |  |
| To make part of the image invisible, create a black and white mask and apply transparency with transparency blend. |  |
| To achieve special effects, try putting the image in both channels and adjusting the alpha channels of different attributes of the texture. |  |
| Additional special effects can be achieved by various combinations of the above methods. | |

| Question: | Answer: |
| I'm using a compressed image format, why isn't my file smaller? | Bryce does NOT use compression when interpreting the image as a texture. |
| Why do I get the error "out of memory" when
pasting an image?
|
There are a couple of reasons for this: #1 You are really out of memory and you can try saving your scene, closing Bryce, restarting your computer and restarting Bryce. #2 You are using an unsupported format. For instance, if you had copied a .GIF image into RAM and tried to paste it, you could receive this error. Take the image into an image editor and change it to 24million colors. |
| Why do I overwrite my existing images when I paste a new image into the lab? | Instead of pasting to window #1 or #2, paste the image to window #3 and you will not overwrite the existing images. |
Materials are what bring your Bryce scenes to life. A wonderfully balanced scene in composition and idea can be destroyed by using bad textures. Hopefully, you have a little better insight now on not only how to use the picture lab, but what impacts this will have on your computer in relation to file size and functionality. If you have some particularly good image texture info, please let me know about them and we will share the knowledge.

This is not meant to be an all inclusive instruction on every possible way to have made the final image or produce the desired results. Bryce offers zillions of wonderful ways to replicate, multireplicate, reposition, etc. in its powerful interface. Experiment!
