RENDERING...Q&A and GALLERY

Modeled in WF2; rendered with Alias ImageStudio.


I'm not sure how Alias stacks up to the advanced rendering module, but I will say that this took less than 4 hours to set up the scene and render to 1800 x 1200.

Hiiii Guys


Nice rendering going out here CP and the guys out here i have a problem howcan i apply the decals which have different background color and when the color of the surface is different i mean to say if the back ground color of the decal is white and the surface color is chrome how can i match the decal color with surface color is there some way out of this prob


thanks in advance guys
 
The radio was modelled in WF2 and rendered in Flamingo (rendering plug-in for Rhino). The are a few questions that I think I can help with:


- The floor I used is just a plain white material with no reflectivity.


- To apply decals in ProE, use an alpha chammel. For example you want your part to be blue, but the text you want to be white, correct?The way I've done this is to create your decal with th background white or black depending on the colour of your decal. Then within ProE, open the decal in the image editor and choose 'image>create alpha channel' set the RGB claues to whatever the background colour is, then save as a TX4 file (i think). If I remember rightly, that should do the trick. Let me know if it doesn't.


- Some have asked about lighting. The lighting I used in my rendering was a light dome. This is in fact many point lights arranged in a dome around the subject. This gives your rendering Global Illumination (GI), don't mistake this for ambient light because they are COMPLETELY different. In real life light comes from the sun and isreflected from everywhere, including the sky, so the light dome simulates the reflected light. You can add other point lights to simulate the sun or other light sources to give somemore realism to your render. The was mention of a book earlier on in this thread, Digital lighting and rendering by Jeremy Birn, I have this book and it is excellent, highly recommended.


- It would be nice if we could upload bigger files as the 50K limit really doesn't do our images the credit they deserve (blowing one's own trumpet there for a sec). Unfortuantely, the normal file size for my raw renderings is usually around 4-5 Mb, due to the resolution required. However, they still look ok when converted from TIF/TGA to JPG.


Hope this helps anyone.

Red Devil - Thats a cool image, very nice indeed... top job !!


pjw, that is pretty cool aswell, I agree with CP that cut-away render looks very impressive.


I am always interested to see what you guys are upto, unfortunatly I`m still not good enough to get to the rendering stage as I am still trying to get my head around modelling. I posted an image or two of a Hinge that I created, but to be honest it was only a very fast render test using standard WF2.0 rendering.


I have just started delving into surfaces, they are incredibly complicated ( im a self taught WF2.0 user, been using for 3-4 weeks now ). Once I get the basic`s of modelling, surfacing etc then I cant wait to join you guys in some pretty cool rendered images.


As many others suggest on this thread, now that we are all back on topic, seeing the images that you people upload only keeps my determination strong, pro-e to a new user can be very very frustrating and not an easy thing to learn on your own, I think if it wasn`t for you lot I would of quit by now

Looking forward to seeing more of your work, and I think that 300Kb per image is not too large, if you are still on dial-up..... then upgrade

Hey Skint,


Keep going, I'm self taught too, it won't take long till you'll produce some cool stuff. PM me if you have any questions on surfacing etc.

Hi red devil,


Only just realised that you are in the UK, wondered why I had such a fast response, guess we are all secret forum visitors whilst we work :)


Thanks for the offer,I may just take you up on it. I am battling away with surfaces as we speak, think I am making progress, just when I think I have conquered it, up comes one more problem.


Where about are you based in UK ?
 
Hi,


I'm based new Watford, a place called Kings Langely. In fact we're about a couple of miles from the Hemel Hempstead fire. You?

Hi Red,


Yeah I know Kings Langely, think I have passed through a few times. Im in a small town called Tamworth in the Midlands, you may have heard of the SnowDome :)
 
hiii red devil


Sorry i cannot get the decal from u r method i mean i was not successful can u explain me in a brief i mean to ask u how do u prepare decals and CP bring me out of this situation ur tips have always worked for me plz suggest me how can i prepare decals and if u have any link where i would find decals it would be greatly appreciated


thanks in advance
 
If you create your decal in PS, you can stretch the canvas so you have a VERY large image; then just fill the background with the background color of your choosing...You can then apply it to your model and let the excess sort of 'fall off' the perimeter of the model.
 
hiii


thanks mfitch for u rsuggestion i hope iam kind of gettin it now any one more question to u cant we create a transperent background where it matches to color of the surface i wanna just know is there anyway where we can create it
 
Hi,


To get the background to match the object colour, you use an alpha channel, this masks the area of a particular colour that you choose. See my method below.


This is the way i do it. Firstly I create the decal to the exact size of the object you want it to fit on, then using Illustrator, i create the decal with a white background as the white is the easiest to choose when creating the alpha channel mask, add the text or symbols as required and save as a TGA or TIF file.


From within ProE open the new decal file in the image editor. Go to the image menu at the top and choose 'create alpha channel' and adjust the RGB values that match the white (255,255,255) then save as a TX4 file.


Now in the material editor choosea new material, adjust the colour and highlight to suit. Choose the map tab and click on the decal button, choose texture at the top menu and add, find your newly created TX4 file and open. Leave the mapping as parametric and adjust the position as necessary. Now choose the particular surface that you want to have you decal on. That should do the trick.


Hope this helps.

Thanks for the response man i guess i havent tried it out but i smell success into it so lets c hope it works out for me any way thanks again hey CP havent seen much renders from u i mean the small ones (not speakin abt the cars) man wanna learn more from u abt rendering thanks guys again for ur help


bye
 
Here is a clay rendering of a specialized toilet seat design I did earlier this year. This is a complete gray room with no textures added. I always start my renderings on a part with clay renders and subtle reflections or transparencies. The realism will come later.

]lol CP, great job... I can feel my ass warming up already.

It's actually a vaccum seat, it sucks the ass-gas out of the toilet bowl and filters it back into the air through an ionizing pump..
 
LMAO.....so long as you don't get your ass sucked onto the toilet......snigger snigger


Sorry CP, couldn't resist it.
