Water Museum

[jtiscareno]

I am working in this water museum. Had as conceptual spark our surrounding mountains, river and desert.

 

In this first post are the images for the final presentation to get approval (we did, it is now in cd's). Images were done in Accurender 3.

 

Second post will include images done in Viz. Compare and Critique.

 

Thanks.

Now in this post i included the images of the same previous model but this time done in Viz/Brazil.

 

I used the technique that DelfoZ suggested for "fakeosity" but I still dont quite get it. As you can see I have multiple shadows of same elemets.

 

Comments and suggestions from all greatly appreciated in order to start getting the hang of Viz!

 

I have never learned how to render with real radiosity of even with GI.

 

Help!

[ben-csab]

Try to increase the Sample Range of the shadow map, decrease the bias close to zero. If the the shadows looks blotchy, increase the size of the map.

 

Note: Fakeiosíty does not work with raytrace shadows for the light dome.

 

I hope this helps.

actually you don't have to fake radiosity using brazil. brazil can calculate GI, there's no need to fake.

[rivoli]

i'd try just with skylight and one direct light. enable indirect illumination and skylight in the luma server rollout. this will give you GI and ambient occlusion. i'd try with the default settings to begin with, both for shade and view rate. leave just one bounce, i think you don't need more than that for your scene. then set a direct light, indirect light should be on by default. anyway, i think the fakeosity effect you experimented can be achieved just turning on skylight.

Personally I would use different trees, the rendering style is very abstract and they should relate. It would also add more of a personal style instead of distracting the building.

First of all, thanks for help. Ok, first Csaba tried your suggestion with sample range, bias and map size as follows:

 

old now

Sample Range 10 20

Bias 0 0

Map size 300 400

 

Ring multiplier top 0.15, middle 0.05 and bottom 0.1

 

Directional Target light (sun) multiplier 0.3, hotspot 10,000, falloff 10,000

 

Brazil render settings image sampling min 0, mas 2. No indirect illumination.

 

First four attached images seem to be looking better than previous ones, shadow ovelapping is gone but you can still see that sort of blob looking shadow around all of model, sunlight shadow is barely visible. Any ideas???

 

Now to Rivoli, man you even answered my question before I even asked it. Thanks, that is why this forum is so great!

 

Tried your suggestion (last posted image) but as you can clearly see something is wrong or off. Same directional target brazil light with a multiplier of 2.0, hotspot 10,000 and falloff 10,000; with advance raytrace shadow. Rest in default.

 

Turned indirect light and skylight in Luma Server and turned of area and other in same spot. View rate is 15 and Bounce is 1. GI min -3, max 0. Rest is default.

 

As you can see is not at all the same sort of look as the other, specially shadow of drect light is to dark, and rest of image is to dark. Any suggestions???

Craig, landscape has to be native to our area, as you can see they are very spares since they are desert plants. I know that with imagecels plants of the desert it could look better if done in photoshop, ghost and what not. But it is kind of difficult and time consuming when you have like 20+ images to do.

 

And can you elaborate on the "distracting with building" comment.

[rivoli]

well, if i understand correctely you enabled indirect illumination but turned it off for area, point light and skylight. those should be also enabled otherwise i think you'll have your scene illuminated just by default lights. i'd use brazil shadow instead of advanced raytraced. i'd even try with a brazil area light and its own shadow.

[rivoli]

your image looks like a scanline one, that's weird. did you disabled anything else?

[jtiscareno]

Man Rivoli, you are great help!

 

Followed your advice and used brazil shadows on direct brazil light. Turned skylight in direct and indirect illumination, turned other stuff in those two on. In misc. turned off deafult lights, is this ok or those it matter?

 

Direct light is 1 in multiplier, and rest is default.

 

I don't want to impose but since we are on a roll, are there any other suggestions in regards to lighting to make the image better. Less blue? Another tint for direct light? I have read about photons?

 

Thanks for all the help.

[rivoli]

in this case default lights don't matter that much since you disable them by adding a light in your scene. well, i'd try to use an area light, this will increase your rendertime a bit, but a brazil area light may be a good try for your scene. try with a rectangular one, chanching size will give you different kind of shadow depending also on the distance between your objects and the light source. i'd try decreasing the direct light's multiplier, but that really dependes on what kind of image you'd like to achieve. other thing, try turning the slightly blu colour of the skylight to white. but again, it depens on your taste and feeling you want to convey. i wouldn't use photons in this case, a thing you can do is increase bounces, 2 for example. this will require higher settings and will need longer render time.

Sorry that post wasn't very clear,

 

I really like the style of modeling and people, they are abstract and add to the conceptual level of design.

 

I think the plants appear modelled in a different style than the building, which takes away from the building itself and is distracting. You could model the plants yourself using simplified geometry and form to continue the abstract feel of the renderings. Which I think adds a nice personal style.

[jtiscareno]

Again Rivoli, your suggestion work great!

 

First image posted is with GI and an area light from brazil. The rest of the images are with that same area light plus the previous direct light, I went ahead and lowered their intensity.

 

I think that they look good. I finally with all the help could render something decent in Viz/Brazil.

 

Another question, how do I obtain sort of the same result but this time only with the regular scanline render of Viz???

[rivoli]

glad to hear it helped. i think the other way to obtain that kind of lighting without a renderer such as brazil, vray, fr (that is without GI or ambient occlusion) is using viz radiosity.

Sorry for the ignorance...But how do you do that?

[STRAT]

to get scanline radiosity you must set up an array of lights in viz that simulate gi.

this is a good script to use too - http://home.wanadoo.nl/r.j.o/skyraider/e-light.htm
