Cthulhu fhtagn

Cthulhu fhtagn
Description:	Horo kindly made me aware of the existance of this interesting freeware tool which generates ivy around object geometry. http://www.horo.ch/raytracing/sys/index_en.html - look under tools and Ivy generator. It's not the easiest of things to get to grips with... and as you can see, my "ivy" has no leaves. This was a deliberate choice since I wanted to use IBL and IBL and lots of tranparent ivy leaves was looking like a fantastically slow render (the materials have to be modified in bryce if you want to use the leaves - set transparency alpha masks and rotate the map by 180 in y axis - if you want leaves). Here (sans leaves) I've also used Horo's test card hdr to provide the ambient light and the standard bryce sun for the main directional light. The model (such as it is) was made in bryce, grouped and combined - then exported to be picked up by the ivy generator where some time was spent tinkering with the settings - er... by "some time", I mean about five hours... did I mention that it is not the easiest of programs to get to grips with. On the plus side, it is free and also, very clever. Swings and roundabouts.

Nice model, good texture, good render, good lighting.

LOL I made 150MB Ivy object file. Bryce doesn't like geometry that is not Bryce made for some reason, the object was rendering at 24% of the CPU, because I ran out of memory.
Also, if you guys visited blendernation.com once in awhile you would have known about this program much sooner ;P

Magnificent looking construction! Excellent texture on the Fhtagn monument. Thank you too, David, for revealing the Ivy software here on bryce5.com I'll check it out. The vines seem very convincing. Maybe a higher resolution of the texture there will improve the final look of the image even more. The skies you use always fit perfectly anywhere in your works. The only change I would make will be to slightly tilt the camera pov angle upwards to loose the inevitable flatness of the bryce horizon.

Aye, Gat, I'm not much of a web surfer, I only visit a couple of sites regularly, this one and www.urbandead.com and use google images for reference. Richter, it might be the ivy model itself that will need attending to, the material used has no bump component so all the crinkles you see are geometry. You are right about the bryce horizon, for me bryce skies are becoming a real issue, now that we've got better light to play with it would be nice to have more realistic and 3D skies. One thing that I should mention, it foxed me for a while, you need to double click on your geometry once it is loaded to indicate where you want your ivy to start growing.

This is an exellent example what the IvyGenerator can do. An interesting option is to let it grow on a simple cylinder, make the vines very thick, add the leaves and you've get nice special 3D trees. By the nature of it, they are rather flat but occupy about a half circle. If rotated appropriately, this isn't obvious and the shadows won't show it.

Horo got a good idea, if you can put a couple of conels or cylenders in bryce to form a skeleton of a tree (or use latice) and then eport it and grow Ivy on it, you can get an interesting looking tree.

Wow man, long time no see from jesuis. Exporting is simple, you just have to perform a boolean operation before you look to export. Any models you dont want officially glued together should be given their own material. Make all objects a positive and solid when boolean, then group, then collapse. Now you will see that you can export in whatever format you want. Nice to have you back bud.

hmmm

I haven't used Bryce in so long, ha ha, I don't even remember how to make things solid and collapse n' all that jazz. Wow, I should really get back into Bryce again. one more thing, this is going to sound really dumb seeing as how I used to do it all the time but, I forgot how to make things...I don't even know how to describe it but, like for example the ivy, when i add the textures all i get are what appears to be little square papers with a picture of a leaf on them :(. All in all I'll say again amazing picture David Its VERY cool.

The [c] option is for 6.0 and 6.1 - if you are in 5.5 land then you can only export terrain mesh objects. In that case you might have to use wings3D to make your stuff. The issues with the leaves is easier to solve. Set the alpha channel for the texture component on transparent and ensure that the blend mode is blend transparency. Also as a side note, you will want to rotate the leaves 180 degrees in the y axis - that option in the texture editing menu. Otherwise the leaves appear to be on backwards. Pleased you like the image! Any further questions, just ask.

carrara

Jesuis, you've been in Carrara land for a while. Have you anything interesting to show?

Also, get bryce6.1 asap, the new hdr lighting feature really levels up what bryce is capable of, and 6.1 is far more advanced than 6.0. The hdri provides lighting that very closely mimics a basic GI. The lighting changes put bryce into a different league.

Yeah

I really haven't been in any other Computer software land, which is very unfortunate. I will have to look into this 6.1, even though I don't even have 6.0 yet ha ha. I just bought a 3000 dollar SLR camera and that set me back a lot on my hobby expenses. How much does this new Bryce run ?

cheap

It would cost about $70.00. If you purchased your bryce 5.5 from daz as you surely did, you qualify for a reduced rate. There is no 6.0 anymore, it can no longer be downloaded.6.1 is all there is. Get 6.1, because when bryce 7 comes out with what they promise are "sexy" features, it may cost more than in previous versions. It's so odd to me to see bryce sold for a hundred dollars when it used to go for many hundreds of dollars. With tha new camera you bought, I bet you could produce some truly wicked hdris.
