Hi All, I just sketched out some landscapes with snow (yes, I still sketch on paper first), snow on trees, snow on rocks, snow on grasses, snow on everything, and now that I think about it ice too...any tutorials or suggestions on the how's and where's of snow? Any thing is appreciated (I'm just getting the hang of Bryce, these will be my 'first' landscapes) Thanks afore hand...Zhann

Check brycetech.com fire and ice tutorial

Thanks, will do...:)

Zhann, It seems that you can achieve icey terrains by checking light instead of normal rendeer,use light colored procedural textures and increasing bump height in the material editor, but I'm too impatient to test it our. it turned what was a 5 minute quick test render into an 11 hour test render. I aborted before it got through - wish I'd have saved a pict of it now. Just a thought: offsetting a copy of your tree etc., making it a whitish texture and inreasing bump height and combining them as a boolean might work. BTW your gallery images look very good. - TJ

yes I heard a similar one Duplicate everything in the scene, group and nudge up slightly - add snow tex

Thanks TJ for lookin' at my work :), and I'll give the duplication thing a try, BTW, I live in Colorado so snow is here already, and there are great mountains to use as models, kinda got me into thinking snowscene... Zhann

Can trees be boolean objects? (as you may notice, haven't gotten to that in the manual yet :)...)

Bryce Forum Coordinator....

If the tree is all one group you can boolean that group with another group or object. In B5 I don't know. Trees were one of the things they updated for B5. - TJ

No, trees in bryce5 have no boolean abilities.

Yup, I have B5 alright, had to ask here just to find the file menu bar, they failed to mention how to access it in the paperwork, :p...

Darn!

Could I just group two trees (different textures), one slightly offset from the other to get the effect?...

Zhann, Well it's all an experiment at this point. might as well try it. Can trees in B5 be disassembled in any way? You might be able to work with that if so. If worst comes to worst you could import a tree created in another app unless this is for the all bryce challenge. I think Virtual Tree has a few neat trees in Renderosity's freestuff you could use to try with the ideas presented about booleans. - TJ

Not for anything special, I do landscapes in acrylic and I wanted to do some digitally, see what can be done in B5...I've done some in Terragen, but I can't get what I'm after...soooo, onward and upward, I'll see what happens, I'll see if I can take 'em apart and reassemble...what could happen after all?...

You can apply a completely transparent material to the trunk of a tree, then apply ice to the leves and offest it just a little bit.

Done! Look for a strange image in the next few days or thereabouts, possibly, maybe, just don't laugh...

Zhann, If it is half as good as your gallery images, I don't think anyone will be laughing - they will be too busy picking their jaws off the floor. - TJ

I can only hope to be as good as you guys someday, I've seen some really amazing stuff...

Zhann,
I have a looong way to go before I can be considered one of the "you guys". I'm working on it though.

Speaking of which could you check out the star field in
this render for me and tell me what you think of the starfield itself? it's actually a textured dome and I was wondering if it looks even a little bit like a sky full of stars? I mean it looks ok to me but I sometimes fail to be objective about my own stuff.

Looking forward to your pic, Zahnn. I tried a snow pic ages ago, and gave up on the trees in frustration.

I tried a snow scene once in B5, and I figured out a real easy way to put snow on your trees.

First, take all the leaves off of the tree by reducing the number of leaves in the tree lab to zero. Then instead of using a trunk material for the tree, use a snowy texture from the "Plains and Terrains" group. If I remember correctly, there are a couple that have a rock texture that look a lot like bark. You may have to play with the colors in the DTE and change the texture from "World Space" to "Object Space" for it to work, tho'.

Hold on, let me see if I can find the image...Ah, found it.

If you look closely, you can see the snow on the tops of the branches. If I remember correctly, that's how I did it.

Hope this helps!

Mike, great pic, I love the distant mountains, and the tree limbs do look like they have snow on 'em. I was thinking more of coniferous type trees, but now I think I might try a few deciduous also... thanks for the looksee... Zhann

BTW Zhann, you can make a transparency layer in the material itself.

Here's a side-by-side of the orginal tree and the "winterized" one. The leaves on the snowy tree have a multilayered texture applied...I will upload them soon so you can mess around with it. The snow on the branches was made by duplicating the tree, then setting leaves to zero, so I just had the trunk and branches. Then I applied the "iceberg" preset under water and liquids. I offset the tree .15 BU up and then moved is slighty away from the camera so the trunk would not have white gunk all over it.

Oh I forgot...I made the iceberg tree a bit smaller as well. Here's a close-up. You'll notice that it's still not perfect yet, but it works fine for trees at a medium distance.

Wow, that's really good! I'd love to play around with it. BTW, just for reference, this is what I'm aimming for (see image) do you think it's possible? I took alot of reference photos last winter for acrylic landscapes, but I thought I'd try them in Bryce...

For that much snow, you might try rendering the tree with a distance mask, then open i in photoshop and stagger is a bit. Then back into bryce import as a lattice, clip, and stick it over the real tree. I will have to try this.

This is the best I've come up with so far with about 20 minutes of work. 1. Create (or load) tree from tree lab 2. With tree selected do a distance mask render, save image. 3. Create lattice and go to terrain editor. Load image and invert. Play with smooth and sharpen, etc until you get something nice. 4. Position and size the lattice until the branches are just laying on the tree branches. 5. Apply snow material. Only works from certain angles so may not be good for animations.

Here's the latest permutstion from me. Unfortunately the render times were way less than fast. This image took 35 minutes and I have a fairly nice machine. I think it is just the material I used though.

Hey, I like both of those, will try both ways...Oh,BTW anybody need reference photos of stuff just ask, photography is my second artform...
