Changing materials resets model scale

[spara]

I have scaled a subent down with model_scale_factor. Changing diffuse_map using setMaterials in a script resets the subent to the unscaled size. I probably should not do that.

Did you mean 'it probably should not do that?' If so I agree.
Out of interest did you apply model_scale_factor to the sub-ent itself, or was it scaled down as a function of scaling down the model to which it is attached?

Yes, it should have been it . I applied the model_scale_factor to the subent itself and the mother was not scaled. Then I changed the material of the scaled subent and it changed to it's unscaled size.

Did you sort this out?

Sort of. It's for the Station Ads OXP. I use frame and screen subents that are attached to the dock entitity. And since my modeling skillz are quite non-existent on top of the fact Wings3D refuses to work correctly on my machine, I took some models from YAH and scaled them down in shipdata. All was fine until I changed the material on the screen subent and it switched to it's original size. Luckily the screen model is so simple, just a rectangle, that I could scale it down by hand by altering the vertex numbers in the dat file. So yes, I'm good for now, but this probably needs fixing anyway.

Ah, OK, thanks. I'd guessed what you were doing
The reason I asked was because I was possibly considering a similar application in the future. I already have a scaled (in shipdata) model with sub-ents (the Cobra2 in X-ships) which has a scripted materials change but as far as I can see that is OK - I probably should go and check though.
Either way you are right that this should be fixed, as It clearly isn't right. Mind you it does open up some intriguing possibilities....

I think it works if the whole model is scaled down, but if it's just a subent that has been scaled down then it seems to go wrong when materials change. And yes indeed, this scale factor is very nice property .

This looks really nice.
And I'll just ask in this thread, because it is probably somehow related:
Any problems changing the diffuse_map on subentities via script?

No problem at all. Here's a snippet from Station Ads:

Code: Select all

...
var newAd = worldScripts["ad_resource"]._getHorizontalAd();
ship.subEntities[2].subEntities[3].setMaterials({"yah_griff_no_shader_screen.png": {diffuse_map: newAd, illumination_map: newAd, illumination_modulate_color: (127, 127, 127)}});
...

The script is attached to the station and the ad screen is a subent of the dock. So ship refers to the station, subEntities[2] refers to the third subent (dock in this case) of the station and subEntities[3] refers to the fourth subent of the dock.

Ah! I tried to call a script directly from the subentity...
This will make it a lot easier, anyway.

Does the scale_model work on subentities?

Yes it does. That's the way things work in Station Ads.

hmmh, it say in the wiki, iirc. Good to know.
