Title: Spirit Lake Log Mat (Test Render)
Post by: sonshine777 on February 05, 2008, 07:57:01 am
Here is a quick test render of Spirit Lake with a population of the log model I created.
Detail 3
AA .3

There are a few collisions of the model in the population but not an overwhelming amount. This is a different POV than the other St Helens image and less developed on the shore.

All in all I think the test was a success.

This is still a small number compared to the original blast in 1980. Over ten million trees were blown into the lake.
Since then some were taken out for lumber and some have sunk to the bottom and began to petrify. Most of the trees that have sunk had the root ball still attached and have planted themselves standing up on the bottom.
So what you have is a forest of trees that is at the bottom of the lake that is petrified, (or well on its way) all in 28 years.

Pretty cool.  I'd say the logs needs some sort of water flow around them, unless the water is really that still.  Not sure how this could be done, without functions.

The ripples can be done with an image mask and a displacement shader, which is what I will do when I am satisfied with the logs. This was just a test to see if the model would populate realistically on the water.

@sonshine777 - Okay.  I see that.  Some things you might consider -

The bright spot I agree and I will be working on it. It will be addressed when I do the closeup surfacing on the mountain.

But the Steam/Smoke actually should be more dense in order to match a plume of that size.

Sonshine, I understand.  Good point.  And maybe I wasn't expressing clearly that I think the edges of the smoke should be less dense.  Smoke tends to find less density on the outer edges...or maybe I should just look this up on Google Images.

Here is a link to the 2007 review report/visitors guide for the park, it has some good pictures of what it looks like today and some from the original eruption. I am still making it too pretty, which is what I'm trying to fix. I want to make the final look as rugged as it really is. Which means making some models of broken of trees.

The whole site is filled with good information about Mt St Helens.

Good one..well a great start...maybe the logs need a bit of charred texture as at least some should have been burnt...Over all a very good scene and a wonderful log setup...thanx for posting that one...sure to get use in future renders of mine I'll teel ya.. ...

There really wouldn't be much char for three reasons:
1.) The speed of the pyroclastic blast that hit the trees was going somewhere between 200 to 300 mph not giving the tree time to be burnt. The trees that didn't get blown down did burn to some extent; the falling ash snuffed that out after a while.

2.) The logs then got covered in ash after being blown into the lake.

3.) After 27 years of bobbing around in the lake have knocked off any bark or char that might be left.

This is really impressive! 

What did you create the logs with?

Cinema 4D RD8, exported them to 3ds (Cinema 4D RD8 doesn't have a great .obj export, no textures)

I then washed the 3ds file through PoseRay (on the gentle cycle of course ;))

The only thing that I still can't figure out about PoseRay is how to retain the scale of the original. The models are always huge. So I just rescale them in TG2.

Looking good. Nice reflection on the logs and as you say the intersections aren't that noticeable unless you specifically go looking for them

My hope is that as I build on this the foreground will have some broken off stumps (more ragged than the one here) surrounded by some new growth etc...

Here is the second POV I have been working on. Still testing things ;D

Ilike this one better, though I think you should make the mountain (volcano, what ever) more the center of the image.

just a small critic...if you can manage, you can have some dead areas around the dead tree for more realism....and why so many logs??....is the volcano throwing off the logs??? :D

Yes as a matter of fact. :)

Looking fine at this stage, man!
I reckon you should go with the 2nd POV, although both are looking good I think this one's the better.

Thanks.  :) This second one has always been the preferred, I just thought I would see how they both looked. I really am looking forward to the final version, so I can crank up the settings.  ;D

I like this second POV, too. 

Are you going to sell the final?  Something to think about on this site...copyrighting, etc.

I like the lighting on the logs a lot better in the 1st image you posted. Looks more realistic. Very, very nice in fact. :)

I really haven't thought about selling it. I have lived with Mt St Helens in my backyard (60 miles away) for 23 years .  It has always been a dream of mine to recreate the stark beauty of the post eruption landscape. TG2 has opened up the path the possibility of attaining that dream.

Who knows selling it may be an option but I want to get it closer to final.
