I updated my latest script https://www.scriptspot.com/3ds-max/scripts/easy-turntable
the other day and I need to add some error checking to the section that allows you to pick a Vray Physical Camera.
Rather than just use a try catch, I thought if they are using a Vray camera why not set the renderer at the same time you click on the radio button.
If they don’t have Vray installed then just disable the radio buttons and keep the default to a standard target camera. (How do I check this?) ps I know how to disable things.
- Is there a method to check if Vray is installed, regardless of which version of Vray is installed? ie 1.5, 2.0.03 etc
- I know enough to be dangerous but not enough to actually think like a programmer yet! so any thoughts on how to best implement these ideas would be appreciated.
- I had the cameras in separate functions originally, and just called them the via the radio buttons’ case statement is this the preferred way?
- Saving the Tangents in/out state prior to changing them.
- The code can be looked at via the above link.
Thanks Luke
Edit: Although not uploaded yet, I have solved some issues including saving the tangents state prior to changing them, all I really need now is how to tell if Vray (any version) is installed and the best way to disable the radio buttons if it isn’t installed, and if using functions would be better practice.
I don’t have time at the moment to read the code or answer the other questions, but about #1:
vray != undefined
Thanks lo
It’s not that simple is it?
I was thinking to check if Vray is installed on the machine or not, then a callback may be the way to go, this way I could disable the radio buttons before the user got the chance to test out my try catch() statement.
What do you mean? I’m afraid it is
If you want to be EXTRA careful, you could use:
[B]
classof Vray == RendererClass
[/B]
to make sure no “genius” has defined vray as some other global variable in their script.
What do you mean? What kind of callback? Aren’t you the one who creates the dialog?
If so, just check if vray is installed on the rollout ‘on open’ event, and if it does, enable the radiobuttons.
Of course that’s it! woo hoo “on the rollout ‘on open’ event”
Sorry for my dumbness I’ve been at this script all day and I’m loosing the plot I think :banghead: I can think of hundred ways to make everything complicated without any sane reason at all.
No problem, we’ve all been there
Thanks halloween very useful
aaarrr Bobo, is there nothing he can’t do?! :bowdown:
I guess I’ll explain my confusion with Vray and if it is installed and which version it is.
Using the listener and renderers.current I get back (on this machine) “V_Ray_Adv_2_00_03:V_Ray_Adv_2_00_03” making me think this call to Vray was limited to this particular version. Using this will get you the Vray renderer so I assumed I was limited to just this version. (Does this mean the there is a shorter way to call “Default_Scanline_Renderer”)
I had similar dilemma with the Vray Physical Camera and the way it responds in the listener as well :surprised
Who woulda thunk renderers.current = vray() worked
Anyway, thank you everyone for your help the final version of the script can be found on my blog (link below) until I get it tested on other machines and versions of max, vray etc when I’ll upload it to scriptspot.
None of my scripts are commercial or for profit, they are free to all, and unencrypted.
Be warned, the listener lies and is probably a conspiracy of some sorts!. After all it couldn’t be me, could it?..
