City test

[Henry Blewer]

Thanks. I am glad you linked to your work here. More options are always better. I am looking forward to your next musical endeavor.

Je connais un site qui a des avions en 3D, mais je sais pas si tu pourra prendre dans ce format 3ds.

Merci, this looks like a good  site.  Nice find!

Oshyan, I did not run the city object through PoseRay. I noticed that the object scale settings using the populator scale the images as well. Since the scale settings for a single object does not scale the images, I tried loading the city as a population. When the population size and the object scale settings are the same, this produces one object. I found it strange that a single instance of an object does not behave this way. It would be a nice feature for newbies trying to use objects if the images scaled with the object size.

Anyway, it's a nice work around. I am getting ready to try this with other objects.

I'm not entirely sure I understand what you mean here. Perhaps some rendered example images would help. As long as an object is UV mapped properly, scaling the object should scale any associated texture maps. If it doesn't, then that would certainly be a big, but in brief tests here I can't replicate that problem. Perhaps there is a UV map issue, or UVs are being treated differently in a population vs. single object? Are these objects even UV mapped, or are you using some other kind of projection for textures?

Oshyan, I think the problem is more a Blender thing. All Blender objects, when imported into Terragen 2 are 1 meter total size. Blender does not use real world measurements.

I am rendering another scene now. I will make a simple object in Blender then import it.

[Oshyan]

Regardless of the original scale, scaling as a single object or in a population should do the same thing, as far as I know. So even if Blender's scale is messed up, there may still be a TG2 problem being shown here.

Ok, let me mess around a bit. I will let you know how I make out (with images). I may not be until tomorrow, I have to go to work soon tonight.

[Henry Blewer]

I had to run this one through PoseRay. I built the model in Blender and used a cube map for the image texture. If I did not use PoseRay, the image did not have UV coordinates.

Tomorrow, I will try a population test.

[Henry Blewer]

This is the population test. I had to run it through Poseray. Apparently the city builder creates UV's automatically; something I never bothered to learn in Blender, yet...

Anyway, it's been a fun experiment. Any resemblance to an actual person is purely because I thought it was such a fun picture!

[Oshyan]

So the question remains - is there a difference in image mapping between population and individual object? Judging by your examples there isn't, which is what I'd expect...

- Oshyan

[Henry Blewer]

I no longer believe there is a difference. But now I am intrigued about learning UV mapping using Blender.

What I do not understand is why scaling works without any extra work in object populations and not for a single object? I read that scaling single objects will change the mapping so it no longer 'fits' the object correctly. This was some time ago.

Anyway, I intend to keep experimenting with this. The T2 render features are too powerful not to be used.

[Oshyan]

I'm not sure what "extra work" you're referring to.

- Oshyan

[Henry Blewer]

Using PoseRay. It's an extra step.

[Henry Blewer]

Is the Terragen 2 tgo file format available to people to use in other apps? Maybe the people at Blender will include the import/export of this object format in Blender, if asked.

[Oshyan]

TGO is a proprietary format for now.

Do you mean that PoseRay conversion is not necessary for objects in a population? This quote from your previous message is confusing "This is the population test. I had to run it through Poseray."
