Rotary Valve Endplate
Read 9723 times
* February 06, 2012, 05:29:34 PM
Hi everyone!

I picked up a copy of 17.2 Pro about a month ago with the intention of working on my 3D skills, mainly for promotional material/ cutout pictures and the like for my company.

It's been pretty frustrating working around TC's little idiosyncrasies at times, but this forum has been a godsend, and all your renders extremely inspiring, so I figured it was about time I did the right thing and started contributing myself!

I've been working on a rotary valve. It's not complete yet, but I though this particular part might be a good place to do a little experimenting on the rendering side.

It's really the first thing I've attempted to render properly, and while everything I've learned from here has been invaluable, I still feel like I don't really know what I'm doing!!

There's probably no real relevance to how the completed thing will look, the lighting is maybe a bit too busy for a brochure or similar, and I've pretty much left the surfaces as unpainted plain metals, but as an experiment, I kind of like the more dramatic look!

All the same, if any of your trained eyes spot anything there that might help me improve, I'd love to hear it. I'm on a steep learning curve and eager to improve fast, so even if you'd like to criticise, don't be shy, I have a thick skin and would appreciate the input!

Enough waffling, here it is:

James.

"...about a month ago"?!!!!  Don't you just hate how fast newbies show the rest of us up!  Jokes aside, great drawing and rendering work James.

Thank you!

I hadn't even noticed that, but now you pointed it out, it seems obvious!

To be honest, I've struggled a little bit with the lighting. So far I've just used the standard defaults, and removed the lights I don't want, or altered the intensity of them. Every time I've tried to physically place them, the results have been poor, so clearly I have a bit of work to do. And as for luminances, a complete mystery to me!

I've attached a cutout of the bearing in the endplate. I used a different HDRI, because the reflections look pretty good, but as the tones are more muted I've found it hard to make the image more dynamic.

The image has the best reflections when only an ambient and headlight are used, but the overall image is too dark. When I bring more lights in (as in the attached file), it's brighter but still lacks a little sparkle.

So yes, I think you're right, clearly I need a bit of time invested on the lighting side. thanks for the observation, much appreciated.

Joking or not, thanks for the kind words!!

I'm a long way off the standard of some of you guys yet though! Turbocad didn't even want to fillet the arms on the endplate for me without a lot of fuss, I have no idea how you got those organic shapes on the wing of your jetbike, very impressive!!

Thanks as well Don. I'm particularly impressed by how you manage to combine photorealism in your renders with a clarity and coherence that you'd normally expect to see in a more graphic style presentation. That's definitely missing from my renders.

And Darrell, the first 3d model I attempted was my bathroom (on V17.2 Deluxe) to try out some decorating ideas. All I can say is that it didn't look much like yours!

Thanks guys.

James,

Modelling is generally the easy part.

Lighting and material settings are the hardest things to get right......its a trade off on the rendering time/quality....Raytrace Full is quick if not taxed to much with the environment/luminance settings. I am using a mixture of environment/Luminance and standard lights...


The Advanced Rendering is not capable of much at the moment because of the memory issue and speed which should be sorted to some extent in the TC19 release. I hope the presets will be better too.

Thank you.

I liked your pump shaft very much. I have  few similar items that I could potentially have to model, so you've set a very high standard for me to aim for!

I agree that those two lights are often sufficient. Be aware that you can control their brightness: Go to View>Lights; select one (being careful not to turn it off while selecting!); click "Edit"; click "Light"; adjust Power and/or the color; click OK.

The bearing looks very presentable.I like.As a tip if you visit Don' site he has a tip for chrome if desire.

Thanks for the advice Henry, I will certainly experiment with that.

wd, thank you! I had seen that tip, it was very useful.

Well, I've finally got a chance to work on this further.

I could barely get this model to load before, and couldn't even get a hidden line render let alone anything else, but now with 64 bit I can work on it easily :)

I wanted to fiddle too, so its all in one file, no xrefs or blocks.

Very much a work in progress still, I'm not satisfied with the materials yet. I made the paint finish, and used a height map for the cast texture on the cutaway, but the metallic surfaces need some work, I'm not really happy with them yet at all.

The lighting is just an intermediate sky luminance and a ambient light. Again, still working on that, the lighting is probably the thing I struggle to get my head around the most!

I tried to save to a BMP, but it messed up and stopped on an image halfway through the render, so this is from a screen grab.

Oh, and for anyone who is wondering what is going on with the valve, we specialise in making wear resistant products, so thats an alumina ceramic lining inside.

Any comments welcome, positive or negative. It all helps :)

Very nice model. The dark material makes it difficult to make out detail in the area indicated in the attached image...

Thanks both!

Henry, I agree, but everything I tried to brighten that area up was causing the chrome shaft to glare. Really, the shaft isn't chromed, but none of the other standard materials really give a realistic effect, so until I do some more work on the materials I thought I'd let it slide!

Same with the bare metal on the valve body, it's not very realistic, and too dark without overly powerful lighting,  but out of the standard materials seemed about the best.

A lot of tweaking to do yet! :)

Just an observation, the fasteners of the cover outboard of the three single-row bearings, are underneath the legs of the spider carrying the most-outboard bearing.  Rotate them 60 degrees for drill and tool access to the fasteners for manufacture, assembly and service.

Hi Murray!

This is indeed true.

On this particular valve there are lip seals, but often air purge seals will be used instead. The connectors are usually between the legs, which is why the tightening bolts for the seal clamps are often underneath the legs.

And yes, it is a pain when it has to be like this :)

A lovely bit of modelling, I do like to see cut out views and you've shown it of very well.

Excellent work

I especially like the cast iron materials on the cut out.  I have seen and broken a fair amount of cast iron over the years, and this is almost exactly what it looks like.

Thanks Dave and Dan!

I found a good seamless cast iron texture on the web, so used that as a bump map.

I was considering trying to be more creative with the geometry of the cut, so the body would actually look like it had been broken, but my head started hurting when I actually thought about how I might do it! It's something I might return to in the future though...
