Residential Apartments

[maurocar]

Hi all,

 

I am new to 3d MAX and Radiosity. Just started tutorial lessons 2 weeks ago. I had some 2 years experiance usin Viz 4.2 but never had any lessons. I designed an apartment block with AutoCAD and linked it to MAX. The 1st image without material is in radiosity and using the sun as a light. Mesh is 250mm.

 

The other 2 images are rendered in radiosity and I only applied few materials. In these images I also used Regather Direct illumination and increased the mesh to 500mm.

 

Radiosity for both scenes is 40%. Help and comments are mostly welcomed. Looking forward for your commenrs.

 

Cheers!!!

*as far as i know, radiosity is not working well (or doesnt work at all) on exterior rendering, try another engine..MR or vray...good luck!

*BUT base on the images you posted, it goes fairly enough..try to increase the percentage calculation from 80-95% this makes a big difference.

Hi Mauro,

 

for exterior scenes it is recomemded to use Light Tracer instead of radiosity.

 

give that a try

[arquiteck09]

and don´t forget to put some trees, people, etc, that´s what make the image more real, not only the lighting. Light Tracer would be better choice for exteriors.

Thanks for your help guys. I'm getting mixed up!!! I am trying light tracer but I'm not happy with the results at all. The results are nothing next to my previous radiosity test.

 

For light tracer I used a skylight and a target spot. The colours are being washed out and all looks so pail!!.

Thats not strictly true. Radiosity does work on exteriors, as you can see on the balcony details. Its just that becuase its based around light bounces and a surfaces light / colour energy bouncing off of surfaces, most of the bounces disappear into space. If you were to render it without radiosity, it would look totally different.

 

But ipdesigner is right about the quality being upped, beyond 90 wont really make much diference. Also try refining it at least 5 times.

 

If you are using regather, the mesh size will make almost no difference, due to the way regather works, this counts for the solution as well.

From what I can get as a final product I think that I can do more in Radiosity. It's true I'm at the 1st stage of the project but my 1st aim is to get the building look good that add ppl, trees etc after. But still i'm getting a bit mixed up on which way I shall go..if radiosity or some thing else.

Light Tracer with HDRI lightning works fine too.

Guys,

 

I'm having a problem assigning the materials in UVW map. When I used Viz 4.2 I always had the option 'Collapse All' Since I starting using MAX8 I am having serious problems assiging different materials to the same object.

 

When I start assiging materials, 1st I convert the object to mesh and select the faces and than I set the UVW Map. Until this step I have no problems; problems start when I want to assigin another material to the same object. In VIZ I used to 'collapse all' and assign the material and set a different UVW Map. In MAX8 this option is never visible in the menu and it's giving me a very hard time. Any solution?

 

I am also looking for some good glass settings which I never managed to get. Any simple ideas?

 

Attached I also submitted my temporary Radiosity Light Settings. The Materials when exposed to the light look good, but in shade some strange artifacts show up!! Any idea what this could be?

 

Thanks to all of you guys. I really find this place incredible. I learned so much!!!

I usually use light tracer, with 1 skylight, and 1 omni light to act as the sun, then turn on shadows in the omni light, and turn bounces in light tracer to 1.

 

As for your texturing problem:

 

1) Create a multi-sub object material, and set up your diff materials, then apply it to your mesh.

2) Add a Mesh Select modifier to the stack, select polygons, then select the polygons you want to texture.

3) Add a material modifier to the stack and select the material # that you need from your multi sub object material.

4) Add a uvw map modifier, and set up as needed.

5) after those polys are lookin the way you want return to step 2 for the next polys.

 

Hope this helps

William,

 

Thanks for your help. Worked 100%. In the mean time I'm working on textures and Light tracer (Faster and good results too)

Glad to hear i could help need anything else just send me a pm

there is no collapse all in max now, what you need to do is one of 2 things, convert it to an editable mesh or an editable poly, and you go around to doing this in the following way

 

select the model or part of it you wish to collapse and right click on it. On the quad menu, you'll see the options convert to poly or convert to mesh....

I guys,

 

I went trough a lot of test this week and tried to get some tests with lights and materials. I Shifted to Light Tracer which I am happy with the lights but I still think that it looks unrealistic. I posted 2 images with light tracer. I also read alot on Vray and tried to do some thing too but unfortunately I read alot of tutorials and my rendering was my worst result ever.

 

Any help on how I can tweak light tracer to get a more realistic light? I am using architectural materials. And as for light I'm using as skylight and a direct light with raytrace shadows.

Did you add a skylight to your scene? It looks like its missing the dimension that a skylight gives a light tracer scene.The scene could use a background that would help bring things together a bit, the blue there is taking a lot from the realism of the scene. Oh yea also go to your light tracer settings and move bounces to 1. It looks to me like you have eather more than 1 omni light, or you have the omni pointing right at the corner of the building, and its casting weird shadows on the balcony, might try moving the omni around a bit.

Hi William,

I am using Light Tracer with 1 sklight and a direct light. The drawing is in mm and the settings for the light are as follows:

 

Light

Skylight Multiplyer: 10.0

Skylight Colour: 255,253,245

Direct Light: Directional, Shadows on, Raytraced Shadows

Direct Light Multiplyer: 15.0

Direct Light Colour: 255,253,245

 

Logarithmic Exposure Control

Brightness: 65.0

Contrast: 65.0

Mid Tones: 1.7

Physical Scale: 4000

Extrior Dayligt: On

Colour Correction: On, 247, 241, 232

Would appriciate and help......Thanks:( :(

I normally use an omni light with default settings, except i turn shadows on, the omni would be your sun, and i use a skylight with default settings.

 

in the end i get a render like this http://img.photobucket.com/albums/v519/bmyatt/ny_building1_3.jpg and this http://img.photobucket.com/albums/v519/bmyatt/basrah_5_4.jpg i made these models for bf2 btw, i havent really come up with a rendering system for architectural real life models as of yet. I think the only way to get the realism you want is to figure vray out, and im kinda new to vray atm.

Hey guys,

 

I just did some good improvements using VRAY. I know I have a long way to go but at least I saw some progress myself which kept me going. It's lovely to be with you in these forums. I learned so much!!!

 

I would like to hear C&C on Vray and materials. I am using more or less the same materials as in the other photos but of course since I'm using Vray I changed the materials to Vray Materials.

 

As for the light I am only using i Direct light as my main light source and a Vray light in the ground floor corner shop. The parquet and aluminum are standard 'Multi Layer' materials.

 

I still think that light needs more and more settings to be real. Can some one help me with the plaster materials I'm using for the facade? When I turn the camera having the light from ecsactly behind, the colour of the plaster gets overexposed.

 

I also attached my settings.

You could create a bump map for your stucco tile so that itll show more realism. That wood texture you have on the patio, i would do in concrete or grass, but as for vray settings i cant really help ya much there.
