Title: Wetness
Post by: choronr on September 30, 2014, 02:11:41 AM
A rework of Dune's Mountain Road Complete. Wetness alludes to a dirt road after a heavy rain the night before as a driver traverses a slick, muddy road, hydroplaning along the way trying to avoid running off into a ditch.

•   Dune Mountain Road Complete available at NWDA.
•   Grass clumps .tgo are contained for use in Terragen 3.
•   Dune's tundra heather .tgo models (two different versions used here) available for download at the Planetside forum - do a search.
•   J. Meyer's LR110 vehicle available for download at the Planetside forum - do a search.
•   Walli's Gnarly Poplar available at http://www.silva3d.com/ .
•   Buck Deer; thanks Mark.

Many thanks to Dune (Ulco) for his help along the way; and, to J. Meyer for his help to get the LR110 lights to appear properly.

This has been an excellent learning journey.

It worked out really well, Bob. Great render.

The only issue I now see is the 'conflict' between the water shader in the ditch and the reflective shader on the track, the thin white line. You always have that when they interact. To get that away you might take the reflectiveness at that roadside out using the same 'verge' shader mask (after warping) as feeds the water plane.

Thanks Ulco, will have a look at that. This was a 12 hour render; but, I've got to get it right.

Thank you Walli, this was a long and fascinating trip in learning some new areas of TG3.

Really nice render Bob.
I especially like the vegetation.
Too bad about that reflection line thing,hope you can get rid of it.
Keep it up!

Thank you Jochen. I'm trying to find the connection that causes the issue.

I especially like the look of the grass along the road on the right side.

Post by: choronr on September 30, 2014, 10:22:39 PM
Thanks Michael. That is the grass clump .tgo you get with Terragen 3. Size it and color it to your liking. With close spacing it makes great ground cover. It works well for distant shots like this. However, for close ups, use another model.

The vegetation is very well done, all in all a very fine image. The lights in the rover came out great.

Thank you sir, this was again, another great learning experience. Yes, thanks to Jochen and to Ulco for all their help. Still trying to correct a few things.

Very nice scene, I really enjoy the varying panorama of vegetation broken by the road.

One thought,  it's been driving up a wet dirt road so much mud spatter must be shown on the vehicle, tires, lights, windows.

Thank you. I will be working trying to get some mud details on the truck; and, a few other things.

I looked at some reference pics, and it seems to be that the shadow directly under the jeep should be darker, and the distant shadow should be lighter..?  ???

Good point. Not sure I could change that to look like you describe.
Title: Re: Wetness
Post by: j meyer on October 01, 2014, 01:33:21 PM
The lighting in N810's example is completely different compared to
the lighting of the scene.There you have indirect lighting almost exclusively
and that causes shadows that differ quite a lot.
The other thing is that the mud is rather reflective,which makes a difference,
too.In "reality" and in TG.

yea I couldn't find an example with the same lighting...  :-[

You could try a high sun with a huge shadow softness for some dark shadow under the car.

Thank you Ulco; I'm assuming this would be a second sun?
Title: Re: Wetness
Post by: Dune on October 02, 2014, 10:45:00 AM
No, the main sun. Remember my tunnel with the landcruiser? I used it there, wiith quite some cirrus coverage (I think) to haze the sun up even more.

I don't recall the tunnel/LC image; but, I give it a try. I'm thinking this will change the whole appearance of the image.
Title: Re: Wetness
Post by: Dune on October 02, 2014, 10:51:31 AM
It will, but it could be very nice. I believe I used a softness of 20 or even 50 for the shadows.

Doing it right now ...I'll be back.
Title: Re: Wetness corrections
Post by: choronr on October 02, 2014, 12:46:29 PM
I tried putting the main sun overhead; but, just too bright. Also, defeated the purpose of having the lights on on the truck. Added a second sun overhead and was able to achieve the darker shadow under the truck and still maintaining the secondary long shadow. The quality of this image is low (and poor); but, wanted to save some time. I think I'll reduce the strength of the second sun from 1 to 0.75.

Finally, hopefully will be trying to achieve some mud on the truck and getting the license to show up.

Many thanks to both Ulco and Jochen for putting up with my many questions and helping me along the way.

Well.... go off line with a Rocket Tab , a browser hijacker that installed itself, issue and come back to find this. Not only a great image in the works but a couple of solutions via Ulco thrown in...thanks youse guyz.

Nice one, Bob. Have you already tried to increase the GISD occlusion weight to get a more natural shadow under the car?

I was about to suggest that. I've been finding 'tween 3 and 5 to be good when using non organic models ie: cars and buildings

Hi Hannes, thank you. I have used a second sun directly overhead at low strength and very soft shadows which has worked out well. Also use GISD. Will be lowering the vehicle a little further down into the soil; and, will try to get mud splashes along the sides and wheels of the truck.
