Create a cube, copy it and then move it away from the original cube and take a screenshot as I have done please, I would like to see if you have perspective?

Try setting the focal length in View Properties to something sensible like 40. The pre-set value is 400 and that is definitely telephoto territory.

Thanks Bill, I am still having trouble understanding this though, focal length and perspective are two different things to me.
Perspective should never be adjusted as you then have varying degrees of perspective, whereas there should only ever be one perspective?

This confusion actually goes back to when I first started with Punch products, I remember a forum poster asking “what kind of CAD program does not operate in perspective all the time?”

Like I say this issue confuses me, if I look at an object the perspective should be automatic and non adjustable.
I use Blender a lot for rendering and animation and you can adjust the focal length of the camera but not the perspective as far as I know, that’s automatic.

Is there a know value for what would be a normal perspective setting?

I always think of the focal length in terms of camera lenses. 'Standard' lenses have a focal length of 40-50 mm and they give a 'normal' perspective. If you have a lens with a longer focal length the perspective is flattened, while a lens with a focal length less than 40 you get an enhanced (wide angled) perspective.

Much appreciated Bill, I might look into using Shark for rendering as it has a great materials database, seems a shame to waste it.

Craig, no offence to the developers but rendering is not one of Sharks strengths. If you are not already familiar with Keyshot I recommend you take a look, it's awesome and you will not regret.

Hi Claus, I used to think the same as I have always used Blender but when I did the first renders of the car I used Shark and it was really quick and easy to get a decent render (perspective issue aside).
The only thing that has been stopping me was the perspective issue, but now that Bill explained it to me I am going to see what I can get with Shark and compare it side by side with the Blender renders.

I will redo the Gibson and see if Shark can compare with Blender on quality and speed.

Hi Craig,

I understand, good luck. I think it depends on your need, I know for me I need to use the right tool for the job. As an example I used to use Maxwell Render but then they changed their copy protection and I could not get it to work for a month. This motivated me to take a look at Keyshot and honestly it completely changed the way I work. During a day I make 10-20 renderings, not for presentation but as a part of my design process and several hours would be spent setting up the scene and ajusting lights. With Keyshot there is practically no setup or light ajustment so you can go from Shark to finished rendering in 2 minutes.

I would love to have better rendering capabilities in Shark, if as an example you design a glass product there is just no way you can do it without looking at it rendered as glass. Having easy perspective setup and realtime rendering in Shark would dramatically reduce the need for an external renderer. However knowing that it's better for an app to do less but more effectively I would probably use my energy on the modelling tools if I was the developer.

You are totally right Claus, the right tool for the job is everything, the person who came up with “a bad workman always blames his tools” was an idiot.

If you look at my #5 post in the Gibson thread over in the gallery you will see the render tests I did concerning GPU and CPU times, unfortunately Shark can only use the CPU so that takes it out of the equation for serious rendering.
Sharks render function is more than acceptable for inflow renders as when I am working on parts I use it before exporting to be rendered in Blender.
My dream is a one program for everything scenario but that’s some way off, I am normally programming cnc’s, running development centres and doing mechanical designs so I have not had much use for serious rendering up to now.

The work that you professionals put out always leaves me in awe as far as the rendering is concerned, it is a real talent that I am slowly getting to grips with.
Blender has just introduced cycles and GPU rendering so it’s more than adequate for my needs, the really sad thing for me is Sharks most excellent material database going to waste.

Hello,

A demo video to explain the Shark-Keyshot workflow.

This duo is unbeatable for me.

And also for the designers community?

:)

I'll turn this back on in PowerPack for the next build for more testing.
