Hi Richard,
Thanks for fixing the lost textures in v7.0.2.1
But now when opening a previous version file, I get 2 Objects Checkpoints after conversion with the File Upgrader.

If I try to go to the first texture above the second checkpoint, I got a message 3 layers were disabled....

I tried exporting the shape and reloading it...same 2 checkpoints.
I tried saving the file with a new name...same thing.
I opened a new scene. Put a box, textured it with 5 textures layers, save it and reopened it. No checkpoints.

If I delete the upper checkpoints, all is OK, but If I delete the second checkpoint, layers disabled.

As it is, I cannot modify any shape created with previous version.

Is it possible to remove those Objects Checkpoints after the file upgrader ?

Thanks.

Because of format conversion (from 6.5 to 7.x, for example), it is not possible to access the layers beyond the checkpoints.

Richard,
Is it possible to recover shapes created with version 6.5 in version 7.0 without having to redo them ?

They should import correctly. You won't be able to get earlier versions of models, if that's what you mean. You'd have to open them in 6.5 revert to the version you want and then open the model in 7.0. Fortunately, you can have both installed on your computer at the same time.

Richard,
I have some problems understanding what you are saying... (Language problem)
I will try to explain more.

"They should import correctly."
If I open my model created with version 6.5.xx in version 7.0, I have 2 checkpoints layers and I am not able to modify layers below the checkpoints.

"You won't be able to get earlier versions of models, if that's what you mean."
By earlier, do you mean that I cannot modify a model created in version 6.5 imported in version 7.0? This is the problem.

"You'd have to open them in 6.5"
Without any upgrader?

"revert to the version you want"
This is where I am not understanding.
What do you mean by revert to the version you want?
6.5.xx or 7.0

"and then open the model in 7.0. Fortunately, you can have both installed on your computer at the same time."

I don't want to modify the model in version 6.5.xx but in version 7.0. Is it possible?

When you choose a layer other than the current layer, you are effectively going back to an older version of the model.

If you want an older version of a model in a file created before version 6.6, you'll need to do this:

1) Install 6.5

2) Open the model in 6.5

3) Choose the version of the model you want (enable/disable layers)

4) Save the model (with a new file name preferably)

5) Open the model in 7.0. You can then make further changes there.

Richard,

A Small remark:
What is the utility of putting two checkpoints layers?
It's annoying and useless as I can remove the first on the top without problem.
The second cause problem (disabled layers).
I prefer not to have those checkpoints.

It's strange that if I have a shape with more than three Apply Material layers in a row (6 Material layers) as last layers, only the first three are kept and the others are disabled like the Genesis I sent you if I remove the checkpoint layer above the last Material layer.

If layers are not disabled, I can modify any layers.

If I have no more than three Material layers, no problem. I can modify any layer.

It's a bug I think.

Two checkpoints are required.

Required for what? If we can remove them or at least one in some cases.

And about this:

Two checkpoints are required because in some cases you can't remove either of them.

Layers sometimes have the geometry stored with them, sometimes not. It's an efficiency issue. You can't know by looking at a layer within 3D Canvas if it has the geometry stored with it or not. So, sometimes you can disable a layer without any problems, sometimes not.

Unfortunately, this is just the way it is. Significant changes where made in the way data was stored between 6.5 and 7.0. It wasn't a "typical" upgrade.

The thing to remember here is that the ability to revert to a previous version is not lost. It just takes an extra step. (in 6.5)

Richard,
I am sending you, by email, a small .3DC shape.
Can you load it in version 7, go to the basic shape and reload all layers. See what I mentionned you and give me feedback.

I am not showing any screenshot here as this is a shape in development.

Thanks.

Sure send the file, as long as you aren't wanting me to look at layers before a checkpoint. Because, if you remove a checkpoint, the results cannot be predicted.

I considered removing all layers before the checkpoint on upgrade to 7.0, but decided against it since there were some circumstances where a person could go back to previous revision.

Richard,

I sent the file but forgot the textures.
I am sending them by email in a zip file.

BTW, the file I sent you is the original in version 6.5.xx so 7.0.2.2 will convert it when loading.

Take only a look to the first checkpoint above the textures.

Further looking at what is happening, is it possible that the 3 missing textures are in the first checkpoint after the six textures in a row?
If, after unchecking this checkpoint, I check it back, the textures are there even if the 3 disabled layers are unchecked.
It's like this checkpoint grab the textures information in the conversion.

If we cannot modify the layers below the checkpoints, what is the utility to convert it to v 7.0?

We must then rebuild the shape entirely.

I looked at the model with 7.0.2 and it seemed fine. Is there some aspect of the model that did not convert properly?

Object layers are considered "temporary", and are intended to be used during the creation of the model. Once the model is complete, they should be compacted (deleted). That's why there are warnings in 3D Canvas if you have an excessive number of layers (100).

If you are using them for some other purpose then you aren't using them as they were intended.

If you want to save multiple versions of an object, or a "base" version of an object, then you should save them as separate files, not rely on modelling layers.

"Is there some aspect of the model that did not convert properly?"

I am giving up on this.

"Object layers are considered "temporary", and are intended to be used during the creation of the model. Once the model is complete, they should be compacted (deleted)."

It's the second time you tell me this.
And I am repeating what I told you.
How could I modify a model in the future if the Object Layers are compacted (deleted)?

When I am putting hours and hours of work on a model, I don't want to rebuild it when I want to modify one layer.

I would like to have comments on this from other users of 3D Canvas.

"If you are using them for some other purpose then you aren't using them as they were intended."

I am using the Object layers to remember how I made it and and to create new version of the model without having to start from scratch.
