Advice on Render?

[Wavada]

Hi All,
Please find attached a 'rendered' model, I created for a client.
I find it fairly fake looking.
Is there a scientific way of creating rendered images, or is it just a matter of 'playing' with settings, untill it looks right?
Any advice is much appreciated.

Check out this post I made (I'm pretty sure the same settings apply for AutoCAD 2007): http://www.cadtutor.net/forum/showthread.php?t=35688

Also, create a CAMERA for your view. The reason is so you can set the camera to a Perspective view. The view you have right now is called an Orthographic view, which does not represent for depth perception, making it look more "fake".

Before you get into the advanced rendering, learn to place lights around the object. If not then create a really good natural lighting by simply typing SUNPROPERTIES and turn the sun on. There's a setting in this Palette called Sky Properties, turn this on as well as it will add to the "realism".

Hope this helps.

That's not bad but like you said it doesn't give that real, picture quality feeling for you or your client.

Rendering is an art unto itself. You can spend more time getting the render the way you want it than you'd spend getting the model ready. And there are a ga-zillion different ways to set lights, sunshine, shadows, backgrounds, camera views, etc....you'll have your work cut out for you to learn all this. But to speed things up for you I'd offer this advice.

Set your perspective variable to 1 so it's ON. Then turn on the sun and sky with the SUNPROPERTIES command, or select it from your ribbon or menu. The using 3DFORBIT set the view to something you like and do an rr command. Then sit back and wait for the rendering to complete.

This is not the only way to do this nor is it necessarily the best method. But without taking the time to learn all you will need to get real profecient with rendering, it will get you started quickly.

I dont know if this will help you at all, but here is a thread that took place about 1.5 months ago. This is how I advance myself in rendering. i hope it helps you as well.

Thanks for all your advice.
I will put it into practice today, and hopefully get a better result.
I just realised I should have thought a bit longer about the price I gave the client. :-(

[CADMASTER1128]

Was the price high?

[Wavada]

Should have increased the price.
Took me about 2 hrs to model this structure. The rendering takes a good bit longer.
But at least I'm learning as I go along. Currently I'm strugling to get even the grass lawn correct. It shows clearly with a tiled texture. I tried to make the texture seamless in GIMP, tried playing around with scaling, but it still is clearly tiled, opposed to seamless.

Please find attached this 'work in progress'.
Slightly better, thanks to the advice regarding perspective view, still far from ideal.
The colours are there, texture, not really :-(
Alltough my camera view looks fine, ones I render the image,(render settings as per adviced) it looks like a primary school colour book, textures seem to be dissapeared.
Tarmac looks good, doesn't it?

I see some "steps" in the curve of the front door trim. You can correct this by doing two things: set the FACETRES variable to 5 or higher (10 is max but you don't need to go that high) and type 3DCONFIG, click "Manual Tune" and uncheck "Dynamic Tessellation". Do this last setting only for rendering, as this can greatly decrease performance, unless you're in 2D wireframe mode.

*EDIT* BTW, the render is looking MUCH better. Try adjusting the intensity factor of the Sky Properties palette. This can really help the lighting. Also, make sure you turn the DEFAULTLIGHTING variable to 0 (aka off) to let the sun light do it's thing with no interruptions.

I am glad to see you are making progress. StykFacE is like a master at this rendering stuff. LOL
